Can someone please identify engine number P11/12299D
The “D” is lightly stamped but I think is a D
Only other possibility is could be a 1 but don’t think it is
Thanks Richard

Try looking here https://www.norvilmotorcycle.co.uk/engrange.htm

If that data base is accurate, it's in the 1967 range.

D should be a numeral, probably 0 (zero), so what you have was an early high-pipe P11 when it left the factory in the spring or summer of 1967.
