Looking for info on a Radiator cap..

Does anyone know exactly what this radiator cap is off?
I would appreciate it.Thanks

 

1931 thru 1933 buick

 

Its off a 1931/32,33 Buick on the 31 the 8 leans back and on the 32/33 it leans forward when you look at it from the side. Buick used this because 1931 was the they started using the straight eight motor.
If you are going to sell it i,m looking one to put on the 30 Buick coupe i,m building and would be interested in buying it.
