Hi Chester
Eddie is correct that it does look like the frame number is 67419 which is listed in the Club Machine Register, however, the model is listed in the register as a TS from 1925 which did not have a three speed gearbox and would have had a simple low/free/high gear change quadrant on the top frame tube. What is also suspicious is that the frame numbers in the 60,000 range are almost all of 1923 or 1924 origin. Your engine and gearbox look like ex CW from their appearance and numbers. The front forks are definitely TS. Looking again at the frame number, the digits are of different sizes and I suspect that it is an earlier frame from a 2.3/4hp three speed model that has been restamped. If it is indeed the machine recorded in the register, it simply means that we have the details supplied by a previous owner.
The second machine shown is definitely CW with the "C" section rims, larger section mudguards, front forks with the boss for mounting the dummy belt rim brake and no provision for the top cross member for a stirrup brake, the frame with mounting for the dummy belt rim brake on the left hand side of the rear fork, drive sprocket on rear wheel, which incidentally is in the frame the wrong way round. Looks like a nice complete basis for an easy restoration. Chris.
