    Gotta love some after Work archealogy: sanding down my Mod A frame to bare metal, I uncovered the stamp number "A211200". What year of production would this indicate?

    All the lengths are the same for pickup, coupe & roadster. Brackets and crossmember designs changed regularly thru production but nothing to affect a hot rod.

    I see one more number.Looks like a 1 . There is an "A" then SEVEN numerals visible before the last star. Total number is in the millions.

    Huh, will drop by the shop on my lunch and take another look... kept trying to get a good shot with no 'flash' in the metal, but had to sand outside, albeit at dusk...

    Highway patrol uses an acid to read numbers.

    (esp. Harley Davidson numbers: acid can detect previous numbers that were ground off previously)

    I've sandblasted, hand sanded, machinist dyed, etc. Those numbers can be elusive!

    Number will end with a star like the one at the beginning. Since the end bit seems to be mostly rust pit, if you can spot a fragment of the star its location will tell you if you need to resurrect another digit there. Here is number finding tech by a really experienced restorer who KNOWS:

    Better take along a friend to do the actual reading, as you'll likely be blind and/or dead from acid spatter...

    If you have a severely degraded final # there, original style stamps are around so you can tickle that a bit for the gestapo to read.
