As part of my Slingerland project, I was able to get ahold of four of the cymbals that were with the set. Supposedly these are the same age as the set (approx 1971) but I don't know if that's correct.
I ended up buying 15" hi-hats (I'll use one as a crash, I already have 14" Mastersounds), 16" crash, 18" Constantinople.
I would appreciate anything that anybody can tell me. Thank you!!!
