Hey Fluff.
A comprehensive serial number log is one thing I have always maintained; not sure why?
I left Rocky in 1989. I did built a lot of Altitudes though under contract in the early 90's. The BB shells came pre-numbered though so I couldn't tell you much about the serial numbers. The ones we did had the angle cut seat collars (top and bottom), monostay rear ends, painted in the Red/Yellow masked scheme.
Hope this help.
Chris
