Nick is the man. He's helped me out in a pinch when I purchased a vintage Marlin rifle that Bubba had damaged when attempting to install a sling swivel--Bubba must have dented the magazine tube with a screw, preventing more than two rounds from being held. Nick was able to repair the damage in about thirty minutes (including disassembly, reassembly, and cleaning) while a friendly employee there showed me some interesting guns that were for sale as well as around the museum/display.
He didn't even want to charge me at first, I had to force him to take some money as I didn't have the skills nor the tools to repair it as quickly or neatly as he had.
If you need M1 Garand gunsmithing he's "the guy".
