Hi there I have a Zildjian hi hat that Is from either the 1940s or 1950s. I wonder if anyone could price it up for me and tell me how much its worth. I can't work out exactly when it's from as there is so much information online and I don't know what's the right one to follow. I also have no clue when it comes to pricing vintage hi hats as I'm completely new to it. If you have any suggestions of who to ask to price it or can help me price it please let me know
