In the auction photos it looked like one front corner would need some glue and a clamp. Is it better in person? No big deal? They look darn nice! Always liked that style. Best to let the kitty get used to them before the new grilles go in! My boys love the old nylon grilles on the C37s...for the brief moment they get to touch them before I scream at them and scare them away. I think I might look for a single Model 19 to use as a scratching post. Or maybe a 901.
