Technical Radiator cap ID help

I have this radiator cap, but not sure what vehicle it belongs to. Looks to be in good shape. The "tail end" is asymmetrical, whereas the typical Ford cap looks to be even-steven?

thanks.

1934 Ford--maybe '33, need a side view to be sure.

 

You can see the partial part number on the underside. Ends in B. I guessing the full number is 40-8100-B which is 1934. 1933 would be 40-8100-A1 0r A2.

 

Here's the best side shot I have here at work, of when I pulled it out of my box of parts and test-fitted (backwards, to clear the hood)...lol.

 

Just googled a 1934 Ford cap. Looks darn close. Thanks for the quick replies. I'm going to throw it and a few other things up on the marketplace.

 

It's a '33 Ford cap.

 

Its correct for '34-'36 truck.Part number 46-8100-B
