Dave's cap is correct, the one on Ebay is not for a Plymouth. Mine also has the wings broke off.

Excellent, thanks for the info I appreciate it. I knew someone here would know.

Gentlemen,
Recently I have seen two different cars at shows both claiming to be 1930U's. Both cars had cowl 2 vents located at the top of the cowl. Tomorrow I am going to look at what a gentleman is claiming to be a 1930U, however it does not have the vents in the cowl. The question I'm posing is: what year had these vents? Also, is it possible the vents were an option, and perhaps that's why some cars would not have these?
Any info would be appreciated as I am not that familiar with the 1930U, I have a 29U which seems to be very different than the 30U.
Thanks,
Dan

Sebastiano,
Nice find!!!!! The cloisonne radiator badge is in decent shape as well...
Take care

Chet,
Thanks for the info. I always learn something from this site!

Gentlemen,
Recently I found a far less than perfect example of a winged radiator cap on ebay. Luckily for me the seller did not even know what it fit on. However I did know what it belonged on, only after hours of looking at a perfect example that I took photos of at the Walter P. Chrysler museum! I realise what I purchased could probibly only be used as a casting but I still feel fortunate to have it. It really shows the rareity of our cars and the even scarcer parts!
Now for my question: Did the winged cap only come on the De Luxe Coupe Model or was this an option on any Plymouth? Could someone educate me on this topic?

Gentlemen,
Thank you for all the good information, this is exactly the reason I joined this forum to gain knowledge, thanks again.

Hello all!
I guess I am one of the newest members of the group. I have owned vintage cars before but never a vintage Plymouth, and look forward to gaining some information from you folks. I have always liked the look of the Plymouths and the fact they are so rare, you never see them.
I recently purchased what I believe is a 1929 "U" Business Coupe.  Unfortunatly I got it w/out a title, however I couldn't resist buying it even w/ the title problem as it is a complete car minus the engine/trans. and is in very good shape, and I even got a few spare parts w/ it but unfornuatly nothing for the missing motor/trans.
I've scoured previous posts to try and answer some of my questions but if I ask something thats already been covered I apologize in advance.
I looked up the "Fedco" number which says it was built in 29, but I also received a body tag w/ the vehicle that states: BRIGGS MFG. CO. Detroit Mich. #322-20773.
My first question did Briggs make the bodies for Plymouth? Or could this tag be totally unrelated?
Also, is there any significant way to differentiate between a model "U" and a "30U"?
Any, info would be appreciated, and thanks.
