I have just won a McCoy 40 Lightening Case version, from Ebay (very good deal!) it looks new, was this a better version than the earlier plain case version, or does the piston need hardening, to use a silencer?
I also won a boxed OS49 from '62, offset plug, once again this was a very, very good deal, its in good condition apart from a couple of the small cylinder head fins missing at the front (anyone got a spare head?
) does anyone have any experience of this rare-ish motor?
Cheers Neville
