Looking for Gibson A50 information

[Jimmy Kittle]

I'm trying to find the age of an A50. I'm sure it is after 1946, but trying to get a little closer if I can. There are numbers stenciled on the back that can be seen through the treble hole. 604 in black and a 3 in red. It also appears to be a birdseye maple back and sides.
Thanks for any information

Looks like an all original 1946 A50. This one is number 3 of the 604 batch.

Thank you.

Jimmy, I might have owned that, how did you come by it if you don't mind my asking?
If not that one, it might have been it's brother.
PM me if you don't want to go public with the information.
