Re:
So these things were made by Litespeed. I think I knew that, forgot it, and reminded myself.
The serial numbers are sequential Litespeed numbers. So this is the 3565th frame build by Litespeed ... happens to to for Alpinestars. That carries over apparently to all frame Litespeed built for other manufacturers. Litespeed can only confirm they made it ... not when. This is apparently an early 1991 according to the former owner.
