cylinder identification

Post  Coventrybob on Sun Dec 27, 2015 5:46 pm

Can anyone identify a very old cylinder barrel/head which I have had in my garage for quite a long time.
I am enclosing some pictures, the link on photobucket is --http://illiweb.com/fa/pbucket.gif?o=0

Look forward to hearing from anyone who knows what bike it was used on.
Thanks.

Bob, I do not immediately recognise it, but if it is a Villiers top end it is likely to be before 1930 and probably early 1920's or earlier as it is single port and screw fit exhaust,
can you measure the bore size it may help ?
There were many vintage two stroke makers early on , including Enfield, Velocette,BSA,and even Triumph

Hi JH,
The bore is 60.5mm dia and the length of the bore is 6 inches.
I forgot to mention that it has casting mark XE12 on the mounting flange.
Thanks.

some more info

Odd size bore that, the 172cc Villiers is 57.25 ( 2 1/4") so that is ruled out, the "E" series engine 196cc is 61mm, so at 60.5 it is too big to be a worn out 172cc and too small to be a 2E ( the 1E has a detachable head), at first glance I thought it was possibly a 2E, but usually these have the number of the model cast on the barrel i.e. IIE, the XE 12 casting No means nothng to me , The 196cc engine, if the bore is actually 61mm and not 60.5 ?, was made in various inlet and ports styles for different motorcycle and industrial use, so may be a variant of this ?
