Replica 1940s Style Tuners

I’ve never seen a replica set like this before, no idea where they came from nor do I think anyone makes anything exactly like them today. Been here for years, hidden away, unused and never on a guitar. Chrome-plated, metal buttons, exposed gears in the 1940s-style, and with posts drilled for both slotted head or solid head guitars, quite cool and extremely versatile. $39
