2 NOS Pontiac 40's? hub caps

[auburnseeker]

I recently bought a small lot of NOS Pontiac parts, mostly from the 50's.  In the lot were some Pontiac caps that date from the 40's and I think some may go back to the 1930's.  I did some google searching for them but it seems opinions for years vary all over the place and when you search the car images I found all different combinations on different years.  That said I would like to know the true year of these caps.  I have a few more I'll be posting later today as well.  If anyone knows of a site that has good ID for caps or atleast Pontiac caps let me know.
