Probably not worth much. Meow's 1960 d/d wrpm-001 is a much better find than this. Better than nothing, it is still fun finding something.
Oh wow! They get real technical with these don't they? Meow did not they catalogued variations this thoroughly. Meow did not even think the die chip in the R was significant, just an added bonus. Guess this clinches it being a legit D/D, even if it is a bit on the small side. Thanks again @alurid .
See @i2i ? People can be nice about what you find. Find something nice so we can all be happy for you.
But did you see the resource @alurid provided? It was a wonderful clincher to have that matching die chip too. It is now certain it is a WRPM-04.
Meow has noticed you changed you avatar again. Meow was just fine with the David Blaine looking dude in his kitchen. Thanks again for the link to the wonderful resource.
