Hi All
This looks like a 3 1/2hp, which should make this a 500cc and not the stated 600cc.
It looks good in its un- restored condition.

It's a 4hp Martin, the giveaway being the slightly radial fins on the top af the valve chambers. On the 3 1/2hp they are all parallel.

Cheers, Graeme

Hi Graeme
I must admit I was only going by the lack of oil sight glass on the crank case and exhaust design.

Indeed. I must admit I am surprised to see fitted what I thought was the later clutch arrangement - I thought the cone clutch was still being used at this point. I also note that the forks are slightly beefier than those fitted to my 3 1/2s, but I have seen these fitted to a 1916 4 hp model.
