Of  50mm centre height the Model P was available in two bed lengths - the short PB1 and the longer "twin-support" PB2. Two headstocks were offered; the 8 mm collet PH2 and the 10 mm collet PH4 both able to take either draw-in or quick-action, lever-operated collet closers. The headstocks were fitted with split bronze bearings were designed for continuous running at 10,000 rpm - their ability to do this reliably being advertised by testimonials from satisfied custom The bearings had plain bores with a taper on the outside by which means a precise adjustment of the clearance could be made. A ball race was provided to take end thrust. The bearings were intended to run "warm" at all speeds with the makers suggesting that, if a machine was to be used continuously at high or low speeds, it would be worth adjusting the bearing clearance to suit. When the bearings were well used it was possible to dismantle them and remove a laminated shim (0.003") to reset the adjustment range.
The tailstock on the "P" was normally supplied with a simple "push-action" barrel but a lever-operated device was an option and a screw-feed barrel was eventually offered as well.
