Mono...That aged look is what serious vintage players love.You cant buy the aging process.Definately clean them up,but removing father time in my books is a no-no..They,re wonderful drums,i hope you complete the kit.
Wayne, you have a good point! Thank you. I'm thinking that it may be difficult to find a bass and floor tom with the same patina, so they look evenly matched? If I don't find a bass and floor tom, then I might sell them and you're correct in leaving them as is. I will try the tips suggested to clean them up a bit and polish them. I can hardly wait to put them back together and try them out. I haven't laid a stick on them yet.
