Well, I never recommend splitting drums, but that set would not rank on the high level of collectability and might be a candidate.
As stated I have never split a set up before, so it is up to the individual.
If it was a rare set in rare colors, I would say do not split it up. (this is what people are doing on Ebay at the moment) but you can do with your property as you see fit.
There have been some heated threads on other forums and I really do not want to start one here.
In the end to some people it is just drums and to others it is a historical time piece. Let's just hope the rare drums fall into the hands of the collector and not the hands of the other.
With anything collectors will always hold things in higher regard and with more respect. Once a market is created then the other person will pop up more frequently since they see a demand.
In regards to the cymbals, 70's A's are not the best in bringing a high value. I did have a 24" inch ride from the 50's, that sold really well on Ebay. It was very thin for a ride and made an excellent jazz ride cymbal. Many players would never think of using a 24", but there are people that will want that cymbal. I would say between $200 and $300 for the ride and $100 to $150 for the crash.
The snare is a 12 lugger so it is probably a Spitfire and not a BR
later called the TDR. The Spitfires also came with 12 lugs and a TDR strainer.
I wonder if our Super Moderator Tommy P can shed more light on the snare and the shell construction.
