If you can, give us a list of the rest of the tubes. Seems like 41's are much earlier than 1947.
I've contacted a local friend of mine that deals with radios of this sort and sent him a link. He'll take a look and maybe can give some insight.
It appears that in your second photo, there is a name at the very bottom edge of the photo. Can you tell what it says?
