Hot Rods Cowl identification

I'm not up on A's, but I did sell one for a friend. It was a oddball 4dr, with all wood framing. I forgot for sure, if it was a Briggs-built body, but I almost think it was. 1929.


Don't know if this helps, but....
here are pics;

Here is a 28 29 ford

 

I have one as well. ***us identified mine as a '28-29 model A briggs cowl.

 

here is a huge pic of the cowl, I'm starting to think it was a Murray body, but I can't make out the emblem at the cowl bottom.
