Old guy here trying to help out my diseased friends widow by clearing out her basement. Among the usual crap that people accumulate after 40+ years in the same house, was a drum set. Any way I now have in MY basement what appears to be complete set. There is a base drum with 2 smaller ones attached to it as well as a cow bell.Who doesn't need more cow bell? There is larger floor drum and what even I know is a snare drum. There 3 symbol sets of varying sizes and a round swivel seat. Other than accumulated dust,spider webs, etc. they appear to be in reasonable condition. They white in color with sort of a prism effect to it. The name I could read on a blue/black label reads Broadway-John Grey-autocrat or words to that effect. Once I clean them up, I can take a few pictures Two questions: What is the best way to clean them and is this worth doing? As they still make the appropriate noises, my 10 year old grand daughter expressed extreme interest in using them to increase audio torture on dear old grandad. There is also a box of sticks, pedals and chrome stuff. My buddy did not play drums but was the type of guy who would pick up anything if it was free. Thanks for any advice you can give regarding age, value etc.
