I'm new to your forum and I am wondering if anyone can help me with something. I bought a old thermogloss maple kit from a man today and it came with a set of Slingerland Deluxe hi-hats. The kit came with some old Zildjians as well and these Slingerland hats. The hats look very close to the other Zildjians. Would anyone know any details on these hats like who made them, are they collectable, ect.? Thanks in advance to anyone who can help. Joe, the Drumcollector.
