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.

We will be wanting to purchace parts for this bike as soon as we can. any help would be much appreciated.
Regards Toby.

Toby,

Timing covers (and dates engraved in them) are interchangeable, but the engine and frame numbers put it solidly in 1914 per the chart located here-

As you can see, there were four models available that year in the 2-3/4hp range besides a special ladies framed model. Basically the T was the cheapest, with the W being the top of the line fitted with free engine clutch and kick starter. Parts availibility will depend somewhat in where in the world you are located, with obviously the UK being the easiest. A fair amount of new parts are availbile for these models to members of the London Douglas Motor Cycle Club.
