unmarked lates 20's hubcaps

[what is it?]

i have 3 of these unmarked hubcaps that i cant figure what for? the one looks slightly different so maybe different year or is a front and the other 2 rears(or vise versa) anyone here know?

Look like Pontiac to me, around 1929. 

But I'm not a expert on it

 

[what is it?]

sweet! thats what it looks like! that means this tail light i found in the same box was probably from the same car!

Caps match according to this. The tail light is only close. The grille looks like the answer to a post yesterday on "What is it ?"

Series 6-29 Pontiac for the hub caps.  One series only, the true 1929 Pontiac.  Tail lamp looks like the correct one .

group 2.679    828741   5.25  Lamp Assembly, tail and signal (chrome)  O/8 30-31, P/6 292-30-31. 

The Door Assembly (bezel to those that do not know the proper GM nomenclature) can have either a bar in the middle like this one or just two half round parts to hold the mounting screws.

There are several tail lamps that look the same but are all slightly larger.

The bracket looks like part of the bracket assembly for the same cars.  It was spot welded to the tube that holds the tail lamp.
