I was recently given a small box of engine parts for my 1925 TS. Amongst them were 2 cylinders, however these are not a pair, one has screwed connections on both the inlet and exhaust ports while the other has a flange connection on the inlet, the other obvious difference is that the one with the flange has more fins between the ports. The bores are both the same size.
Could someone please tell me what these cylinders are off.
Thanks
Marcus
