I recently acquired two sets of Norton engine cases, two of which have numbers stamped on them that leaves me puzzled.
Stamped on the front of the drive side engine case is 20121777P
Stamped on the upper side of the drive side engine case is 20/114656/P
Both have the small breather elbow on the left end of the cam tunnel
Any ideas on year, model, displacement?
