2 80s Gon Bops For Sale

Hello all... Ive been looking around trying to find some info on these drums. I think what I have is a Conga (IC-3000) and Tumba (IT-3000) from the early 80s. They each have a few cracks (which haven't made it up the length of the shell as far as I can tell. Otherwise, the finish is beautiful aside from a few scratches (nothing like what is "standard" for drums of this age). They are really beautiful drums. I'm looking for offers for them and have an idea in my head of what they're worth, so please give me some fair offers, and let me know what you think of them!
