Ken, GREAT example of a honda 9 font !
the hard p[art with 1621 or 1629, which ever you prefer is the fact the last digit appears to have been made to look like a 9.
to me, it's very clear, the last digit was/is a 1. BUT, at some point after the 1 was stamped, somebody added a loop to make the 1 look like a 9. whether is was a factory modification or after retail sales, we'll never know.
as Keith pointed out, we've seen some pretty funky, what appear factory vin changes, to exist.
the owner of the 1621, call me 9 has not answered my questions about the position of the top of loop in relation to the top horizontal arm of the isthe top of loop below and or attatched/not attached to the 1
?
all things considered, until we have factory evidence of vin modification, what clearly exists is a 9 that does not look EXACTLY like a factory 9 font. were that loop not there it's a no brainer for a factory 1, IMHO
