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.

Hi everyone
I am looking for a 1922 3 1/2HP "S1" frame...they are a little different than the normal Douglas frame..if you think you have one email me direct.
I have lots to swap for one if need be....or $'s.
Also any OHV bits of that period would be welcome.
Thanks........Dirt Track.
