Hey long time reader on the forum first time poster.

ive been told this is the best place to ask this question about putting a rough date on my 99F, ive googled and come up with very vague and varying answers from "made after 1891" to "1951 or older" and finally "1957" so i figure you guys got a better handle on this so ill let ya give it a go.

serial # 9508XX
LBC 17I

not %100 on the LBC as it was hard to make out

thanks
