Guess the Tail light

Can any one tell me what car this tail light came off of? It is glass and double bullet shaped. I am trying to find a replacement.
Thanks

 

48 buick if I rember correctly

 

It is a 1950 to 1952 Buick Tail light!! Thank you for the tip. You steered me in the right direction. I have found a replacement.
Thank you again!!!

 

1950-1951 used same for both these years I think

definitely NOT 1948
