1911-1912 Body Number Question

[Retro54]

I'm writing this post in an effort to assist a man who is asking on the MTFCA Facebook page. Seems his neighbor might have a 1911/12 body up in the attic. Apparently the doors and body have the same number stamped in it (13 213) thirteen SPACE two-one-three.

Is the body number for these earlier cars the same as the serial number of the car? I know with my 1915, the body number is different than anything related to the engine or chasis, but wasn't sure with the earlier ones.

Again, just looking for info to help the gentleman out, I know nothing else about the parts and if you want to see photos, you can pop over to the facebook page and see for yourself. I put a link to this post on his FB post so he can see the info too.

Thank you in advance!

Like I told my kids when they asked if they could have something I said "maybe". And when they asked what "maybe" meant I say it depends but its mostly "no".

Beaudette did number bodies sequentially, and Ford numbered engines sequentially. Up until October, 1911 the Body ID tag, or Patent Plate tag matched the engine serial number.
However, according to Trent Boggess, Ford's body inventory room at the Piquette Plant had one door, so Ford used a first-in, last-out inventory method.
I have compiled a database of all 1911 body numbers (focusing on Breaudette as mine is) and have found ZERO correlation of body numbers to serial numbers."

Since engine number 13213 would make it a 1909 . Since "13 213" is not a 1911/12 engine number, it can't be a 1911/12 body if engines & body numbers were to match during that period. Pictures of the body would help
