Can anybody tell me what these are off of. They have 49-50 series 76 written on the back, but they look a little different to me.

 

Thanks Cold War, I've been looking at google images and still have not found a photo of them on a car. I guess that explains it being a one year/one model only.
Cheers!

 

Might be a little late in my contribution to this thread, in any case I'll throw my hat in the ring..
In many cases they look like '49 Olds tails-lights, the lens and reflector.. The top spear is thin like a '49, opposed to being taller and fatter with room for the backup light.
It could be that they are '49 Olds Station wagon, however, the inverted reflector location might rule that out... Bill

 

Isn't There A Difference In Taillight For The "Slanted Trunk Models" And The Sedans.I Believe The Taillight For The Station Wagons Were Round And Mounted On The Tailgate! Hope This Helps. I Believe These Are For A Regular Sedan.Of Course What I Believe And 75 Cents Might Get You A CocaCola out Of Some Machine These Days! Larry

 

that looks just like the bezel for the 1949 Olds 98
