Bill,They are 1976 3 plys. They have the reinforcement rings and the speckle paint. I dont know if they are a rewrap or not. I paid $849 shipped for them so I dont know if this was a stellar deal or not. Sizes 24, 18, 16, 14, 13 and 6, 8, 10, 12 concert toms. It will never be a collectors kit because the 10,12, 13, and 14 toms were painted black inside. That didnt bother me because I was going to put white heads on both the reso and batter. I was talking with Jack @ Lawton Drums about adding the lower hardware for the 10 and 12. I mainly wanted a good players kit, but I also don't want a Beverly Hillbilly set.
Another question, is that bare wood showing through, or just glue stain?
In either case, FWIW I think you got a good deal. I do agree that it wouldn't hurt to try to get some of it back, but if that don't shake out you're still OK. That is a LOT of 3-ply Ludwigs for the money. And, the others that have commented about the different glue as well as the different wrap process that Ludwig used during this period are correct. What I was referring to was the way they did it in the 60s.
So, from the info available, I'd say your set is probably NOT a rewrap. And like I said I think you came out OK. Enjoy. I'm sure I would.
BTW -- If you don't want the concert toms, they do pretty good on eBay (especially the smaller ones). You could get part of your money back that way... just another thought.
