I am pretty desperate for a rear cylinder for my veteran Douglas 1917 2 3/4hp "W" model.   I there is anyone who may have one of these that can be re-sleeved or know where I may find one I would be very pleased for the help.  I have a number of engine parts that I can exchange such as matching crankcases, conrods, crankshaft, flywheel etc. Any help appreciated.

Does anyone have the specifications for the oil inlet valve spring for early 2 3/4 engines - Part number 424.   I have tried to order one from the club spares but apparently Jeff Swan is indisposed at the moment.

The handlebar assembly of my 1931 A31 is integral with the top clip or yoke, and I imagine is similar to other models of this era. As shown in the attached image, there are two square-section cutaways in the lower edge of the bore which fits over the steering stem - one on each side. Can anyone advise what these are for? I am guessing some form of locking washer, with dogs which engage in the cutaways and edges which fold over the faces of the bearing nut beneath. This is just a guess, though and it would be helpful to know the correct answer before I complete the reassembly. All comments appreciated.
