The weight seems about right to me. Remember they didn't make matched pairs back then. So you tended to select one that was a bit heavier for the bottom with a slightly thinner cymbal on top. but the weights were fairly close. They were used for jazz, light pop, small acoustic ensembles and big bands. Definitely not intended for heavy hitting rock or country. The thinner, similarly weighted, pairs often gave more of a "chuff" sound then a staccato "chic" sound you'll hear with heavier modern hats with a much heavier bottom cymbal.

Can't speak for others, but trans stamps are so desirable for their sound, which tends to be darker with more complex and interesting overtones and a nice amount of wash when riding that doesn't overwhelm and obscure the sticking. The sticking also tends to be somewhat woodier sounding, similar to many old Ks. To me most modern A's are way to bright, harsh, and pingy and just sound awful.

Hi there - here's a sound clip of these hats - please excuse the poor lighting.

They sound great, mate!

Thank you Gilnar! I see you're from Prague - will be over there for a family vacation in December. Are there any good vintage music stores to check out in Prague? Have a great day.
