1932 Ford Firewall Identification

I just picked up a Ford firewall that was marked "Model B" (given how other items were mis-identified by the auctioneer , I'm not sure about the marking). It was with lots of misc. Model A parts at an huge estate auction over the weekend. I am sorry that at this point I do not have any pictures ( or the skill to post them).
The firewall looks like a 32 and has " feet" on it. My question is.....can anybody give me any info on how to determine whether this is a 1932....1933....1934 or "other".

Thanks

 

First pic, 32 second 33-34 and thrird late 31 model A.

 

pictures would be a big help

33/34 car are welded in and are completely different than 32.

33/34 pickup are different again

 

And...'33-4 pickup, also welded, looks similar to '30-31.
There are twop slightly different basic versions of the '32 but they are similar and hard to mistake for anything else after seeing the picture above.

 

Thanks for all the great replies. The one I have looks exactly like the first picture, so I will assume that I do have a 1932 firewall with legs and the original sealing on both sides on the top of the firewall.
Thanks again to all the quick responses.
