Hi, just looking for some help to put a date (and model?) to this Birmingham made Sun frame.
Ignore the forks as they're obviously a later addition but the frame number is a bit confusing from the data I can find.
Frame is clearly stamped 477NM on the lh drop out, but all the data I can find shows a only single year letter - e.g. M or N but not both. M = 45/46, N = 46/47.
Any clues? Do I suppose it's a 46?
Will be putting it up for sale on here so trying to confirm the year.
Thanks.
