Yeah, it's one hell of a frame but I bought it for a girlfriend, so it's way too small for me :/
I saved it for a basement price from a hipster who almost made it a fixie. shame shame...
I'll make my money back and then some I hope.
So, back to serials...
H = factory (Honaka)
9 = year (1989)
A = month (January)
and the rest of the digits are just sequential bike #'s?
This is pretty typical for Japan and Taiwan serials right?
