another Snail Drum Question
 

I'm going to be looking at a couple of snail drums for possible purchase in the near future.

Can some give me a few quick pointers on what proof marks etc... to look for.

He says that the only proof marks he can find is a triangle with three circles inside and I can't seem to find that in any ref books I have including Costanzo's

A little help in this area would be much appreciated

Thanks
Jim
