Hey fellas, another picture that hopefully someone will be able to identify the original car they came in.

Mate that dash pic is great! The picture is from the eBay ad, I'm thinking of buying it for my roadster. Something different that you don't see over here! Looks like it'd fit a '40s era roadster real nice. So we can confirm it indeed is a Packard gauge then? I know eBay ads are forever mid ***led / incorrect identification and when it's something obscure like that it helps to know the true origin of it. Posted using the Full Custom H.A.M.B. App!
Like I said, its identical to the 33-34 Packard unit EXCEPT that the Packards unit shows only 75psi. Here is a great site to help id (or find something else you like) https://sites.google.com/site/identifyinginstrumentpanels/home
