1937 Packard brake drum part number

I was looking for a rear brake drum for a 1937 Packard Super Eight for another Packard owner. He has given me a part number to look for (234734), but in the hoard of drums I've been looking through, I am either finding different type numbers or no numbers on the inside of the later model Packards.

I found some drums marked "12" and some marked "14", scribbled on the outside of the drums.

Here's a number I found. I'm wondering what it means:
05264 R
