Of the same basic design as what might be called the "Generic Taiwanese" as sold world-wise since the early 1970s, this version from the early 1990s looks rather different. However, although the lines of the headstock with its curved, embossed cover hiding the top section of the screwcutting gearbox make it look distinctly modern, underneath the mechanical elements remained unchanged. However, unlike the other models with their backgears mounted behind the spindle, on the "Ajax" version they were, unaccountably, set in front. The notes below refer to the standard model - though its likely that the specification of the Ajax would have been little changed.
In its original form the lathe appears to have been built (or copied) by more than one company, and marketed using a number of different names including Carolina, Glen, Grizzly DF-1224G, Enco, Honden Visa, Kin Shin, KS-3.5, Lantaine, Manhattan, McMillan, MSC, Peerless, Warco (under various model numbers) and Wey YII Corp, etc. In addition a modified version was also produced (some branded as "Ajax"), this having the backgears in the headstock at the front of the spindle instead of behind and an embossed, curved cover over the front of the headstock that gave the lathe a more modern appearance. However, despite the cosmetic changes, mechanically it seems to have been identical. Some of the names used were of actual manufacturers - or importers and agents - while others were entirely fictional - lathes sometimes arriving at the distributors with an envelope containing a selection of "invented" nameplates. However, all versions and sizes were of mechanically identical design and construction with common Model Designations being: "1122", "1124", "1224", "1236", "1340", "1327" and 110-2021. The first two digits referred to the swing and the last pair to the capacity between centres - all figures being in inches - i.e. the three smallest versions were the 11-inch swing (6,5" centre height) "1122" and "1124" with  24-inch between centres and the 11-inch swing by 20 inches between centres 110-2021, while the largest was the 13-inch swing by 40 inches between centres "1340". If the lathe was fitted with a full screwcutting and feeds gearbox the Model number was generally given the suffix "B" - most examples found in the UK being so specified. As the lathe seems not to have come from one factory, and to have been in production for as long as three decades, the specifications outlined below may not be accurate for all examples found.
Belt driven from a built-on countershaft (of rather crude but effective construction in welded angle iron) the roller-bearing supported spindle was bored through around 40 mm (19/16") with most appearing to carry an 8 t.p.i. nose thread, though ones with a 4 t.p.i. thread have also been found. The nose socket was a  Morse taper No. 5 - this being equipped with a hardened sleeve to bring it down to a No. 3 taper. Bearing lubrication was by individual oil baths, these being fitted sight-level glasses on the front face of the headstock and the bearings fitted with effective oil seals. Various kinds of oil filler arrangement have been found from simple push-in plugs with knurled tops to flip-lid oilers; unfortunately there appears to have been (at least on most, if not all examples) no means of draining the oil - though some owners report 40-years of use and no fall in the level….

A full-span backgear using helical from gears was fitted and, with the drive coming from either a single or three-phase motor (1 or 1.5 h.p. ) twelve speeds were available that spanned in the region of 60 to 1300 r.p.m. (examples being confirmed with 65 to 1280 r.p.m. and 60 to 1240 r.p.m.).
Often found induction hardened and ground, the deep, well cross-braced 190 mm (7.5") wide bed used traditional V and flat ways - the dimensions of which are believed to have correspond dimensionally to those used on Colchester Student and Master lathes from the 1950s and early 1960s. Although the "1124" and "1224" did not have a (removable) gap bed (for the UK market at least) the others did, with the "1236" allowing a disc 445 mm (17.5") in diameter and 190 mm (7.5")  thick to be turned on a faceplate - the corresponding figures for the "1340" being 470 mm (18.5") and 190 mm (7.5").
Of the dual inch/metric type the screwcutting and feeds gearbox gave 40 Whitworth pitches from 4 to 112 t.p.i and 30 metric from 0.2 to 7.5 mm pitch (one important point, experienced by the writer a couple of decades ago, was the lack of a key to retain the single gear on the standard-fit dial-thread indicator used on the Imperial models. If this slips, as it did on mine, your threading job will be ruined….). Metric-threading lathes had a D.T.I. with several gears: 20t, 21t, 22t, 26t and 27t--though if all could be mounted at once is unknown. Leadscrews on early models were 20 mm (3/4") diameter but on later machines beefed up to 22.2 mm diameter (7/8") -  both of 8 t.p.i. Power feeds were transmitted by a separate 22 mm diameter rod and ranged in the sliding direction from a slow of 0.053 to a fast of 1.497 mm (0.0021" to 0.0589") per revolution of the spindle and from 0.23 to 0.647 mm (0.0009" to 0.0255") surfacing. Engagement of power feeds was by an apron-mounted "semi-gate" control, the mechanism being similar to that first employed on the English "Kerry" lathe during the 1950s Late models are sometimes found equipped with a "third-rod" in place of push-buttons to control the electrical spindle stop and start - the operating lever pivoting, in the usual convenient manner, from the right-hand face of the apron. To suit both American and European markets, the apron could be had with the carriage handwheel to the left or the right-hand side - one, obviously, being a mirror image of the other and the other controls suitably repositioned. While some models have an oil-sight level glass let into the lower right or left-hand corner of the front face, most do not.
Nicely finished by grinding, the compound slide rest used tapered gib strips on cross and top slides and often found with rather well-made and neatly engraved satin-chrome finished dual inch/metric micrometer dials. A useful option was a T-slotted cross slide (a fitting sometimes found as part of the standard equipment) with the cross-feed screw split and fitted with a cross bolt that allowed backlash to be removed as it developed in service. Some, but not all, models has a T-slotted top slide, this allowing the easy fitting of alternative, quick-set and rear-mounted toolposts.
Locked to the bed by an eccentric cross-shaft lifting an eye-bolt and T-clamp the set-over tailstock on the smallest model had a 32 mm diameter No. 2 Morse taper spindle with 100 mm (4") of travel - all other versions having the same travel but with the spindle increased in size to 40 mm - and, for the size of lathe, a more suitable No. 3 Morse taper. Some tailstocks have been found fitted with a large micrometer feed dial - this apparently being a dealer-specified option and not found in the accessory catalogue.
While all sizes of the lathe were of identical mechanical construction, in order to be competitive in different markets the range of accessories supplied did vary from model to model - though were usually generous in quantity and could include a welded sheet-steel cabinet stand with a good-sized chip tray and locking storage cupboard; full electrical equipment; 3 and 4-jaw chucks; 10-inch faceplate and catchplate; 4-way indexing toolpost; thread-dial indicator (check for the missing woodruff key on the gear shaft); fixed and travelling steadies; coolant equipment (with a 0.25 h.p. pump motor); extra changewheels to extend the threading range; chuck guard; spindle bore reducing sleeve; a pair of Morse centres; chrome-plated handwheels; oil can; grease gun; toolbox; spanners; Allen keys; screwdriver and often, though not always, a T-slotted cross slide and dual metric/inch zeroing micrometer dials..
