Also, I'm never sure everyone is talking about the same things The engine number, gearbox number, and certification plate number should all have the same serial number. The frame number might have started matching those three at some point,
The frame number generally matched the plate number from about May '75 (see dynodave's frame chart).
My 7/75 334xxx Mk3 has matching 6-digit frame* and plate numbers.
*The full frame stamp being *850*334xxx* (* = the NVT three lines in a circle limit stamp)
but they don't on any factory record I've seen.
Perhaps because you haven't sought information on a late enough (Mk3) model?
Edit: However, Joe Seifert stated in a previous discussion: "Unfortunately, the records I have do not give frame numbers for most 850s"
Finally, does anyone know for sure that the frame number is unique to each frame or if it is really a frame batch number as some have said.
Going by dynodave's chart that's a heck of a lot of batches, although he does refer to it as batch sequence number but I believe they are individual serial numbers.
