This listing is for one set of six (6) Single line Kluson's from a 1957 Musicmaster. Will also fit Duo-Sonic's. The nickel plate is oxidized. Some turn smooth, some are a little loose, but not skipping.  Good, solid original buttons. However, they are what they are, old Kluson's. They were made to much sloppier tolerances than what we see today and on top of that, they have over 60 years of use and abuse on them. For that reason, they are sold as is. No mounting hardware included.

A note about shipping: While I am offering USPS as so many want the rock bottom shipping prices, I suggest FedEx right now as the USPS is experiencing major issues nationwide. while I don't believe they will lose them, shipping times are often extended due to packages bouncing around facilities, getting caught in loops, and being dispatched to the wrong hubs. As usual, shipping includes insurance, so we are both protected no matter which option you choose.
