What frame is it?
I'm no expert, but dimly recall an explanation of (some) Spesh serial numbers along the lines of:
first letter = factory code
second = year, i.e. 6 = 1996
third = month ABCDE..., i.e. I = September?
Frames built from about Sept/Oct onwards are probably for the next model year.
Someone else will surely correct me.
cheers
