I'm looking at the feasibility of restoring a B24 basket case. Can anyone advise on the possibility of finding a cylinder head and front forks, plus some hen's teeth if pos.

Dean Southall

Perhaps M20 forks will fit and you'll have a better chance of finding them.
Some people with lots of experience of such matters have reviewed the repro M20 forks and suggest giving them a wide berth.

Thanks Dean. There seem to be M20/21 girders and some B21 available. Can anyone tell me if they fit a B24/26 or can be adapted?
I think finding a cylinder head is going to be problematic. Are they very specific to the B24/26 350s or can others be adapted.
Also, any thoughts on the possibility of finding an oil tank?
All good fun!

British Only and Cornucopia might be worth a look.

Parts do come up occasionally, an oil tank and a cylinder head were on a well known auction site until very recently, just keep an eye out.
The B24/25/26 cylinder head is the same for all three models, but for the three years of production,37-39 there were changes to it for each year, although these are nothing to prevent earlier or later heads being fitted. From 1938 two extra lugs connecting to the rockerbox were added. For 1939 a completely new casting with deeper finning was used. Can't think of a head from a different model which would go straight on.
The oil tank was the same for 37/38 but changed for 1939 to the M series shape tank, which I believe would fit the '39 B models as the mounting points are the same.
Forks were specific to B series. M series girders would probably go on but C series both pre and post war types will go straight on and are dimensionally pretty much the same.
Both C and M models share quite a few parts with the pre war B series.
