For the last fifteen or so years, I have been acquiring vintage drum sets through buying some and trading for some. I think that I reached the state of critical mass in 2013 when I had 13 drum set--all mid 20th century American-made drums. My wife and I were empty-nesters, and decided to sell the large house to have a more manageable retirement cottage built for us. I would not have the luxury of the fourth bedroom used for my drum collection.
There were a few months before moving to the new smaller house. I sold off five of the drum sets. Of the eight drum sets that made the move with us, I have over the past few years sold or traded two player's sets for one pristine set a couple of times. My drum collection is now a more compact aggregation of three drum sets and one cocktail kit. I have kept a few extra snare drums. I have not sold any of my couple dozen vintage A. Zildjian cymbals ranging from pre-World War Two to early 1970's. My drum hardware stash has more than enough stands and pedals to outfit about ten drum sets. I may now be satisfied with the stuff I currently have. I say that today. My thinking on the matter may change at any time. Here are the drum sets I have kept.
1963 Black Diamond Peal Leedy 20-13-16-matching Shelly Manne snare.
1968 Lavender Satin Flame Slingerland 20-12-13-16-various snares.
Leedy orphans (40's-50's-60's) White 3-D Moire 18-11-16-matching Camco Tuxedo snare.
