These are made in the 80s and in my opinion have a better feel to them than the modern PingWorks (China) made tuners. The oxidation to the nickel gives a nice patina. If you have a need for these tuners in a more mint/shiney nickel I can be bothered to polish them for an upcharge. It'd take me about an hour with some SIMIchrome polish but it can be done without harming the nickel plating.

They are collared tuners suited for guitars with modern 10mm peghead holes. Guitars with push-in bushings (like Custom Shop reissues) would need some reaming before installation.

The six mounting screws are #2 size (most typical)
