OK Jeff, this is what I can see. I had to break out the 2o foot magnifying glass to get this info.
On the second pic in above post on one side you can see 29A, on the other end same side 75A
Opposite side one end says ONE OR MORE PATENTS (and there are 8 of them) here are 4 I was able to read before my vision went south, these may or may not be accurate but that is what I can see, 3549383, 2687544,2697241, 2756474. I can get the others if you need them. Giving my eyes a break.
On the other end, closest to the clip, 702849 CAN. 52, 55, 58 PATENT PEND.
Here are two pics of the back.
