1 Michiel 2 years ago I am going to check out a Bladwin era Country Club (7576) this saturday. On the pictures of the guitar it looks like the top has some cracks in the finish. Now, I'm told that cracks in nitro finishes aren't such a big deal, but in poly finished guitars you'll end up with the finish flaking off completely. Does anyone know what finish Gretsch used in the 70s? This may be a noob question, but I'm shooting it anyways.
