Although superficially similar to the Russian-built copy this example is obviously from a different maker, and possibly East German in origin. Whilst the machine lacked an integral metal baseplate, and bed bars appears hopelessly light in comparison with the original, the headstock appears to have been robust enough and the cross-slide travel obviously greater. It appears that all the micrometer dials could be zeroed. Like the Emco, the headstock could be removed and fastened to a vertical milling and drilling column. However, this was a very much more complicated affair than the simple plain bar used on the SL1000/DB200 with the head-carrying bracket driven up and down by a screw-feed and guided by a proper, full-length alignment key. A micrometer feed-dial was fitted at the top and what looks to have been an adjustable rotation-dial at the base.
If you have details of this lathe the writer would be pleased to hear from you.
