Thank you very much for the info and compliments, guys.

I love seeing the gems everyone here has. These are my Pops' drums. Thanks!

I happened to find a pic that Martin had put up in the Vintage Latin Percussion LP Facebook group (I believe you're familiar hehe). This particular badge and style appears to be from that period you mentioned. I have to confirm with my Pops, but yours and his have the aluminum rims that it appears Martin went to after the Cuban style bronze/steel rims. I didn't want to post that pic without permission.
Regarding the Cuban drums, his are solid shells, not staves. He thought they were Vergara's with Requena hardware...?
