Grover Open Gear Bass Side Tuner - SINGLE (1950s - 1970s - Brass)

Here for sale is a SINGLE (1) bass side Grover tuner from stomtime between the 1950s to 1970s. I am going to guess late 1960s to early 1970s. 

I recently did a restoration on a 1940s Gibson Southern Jumbo, and instead of a traditional set of 3 x 3 tuners, it had these six bass-side tuners. 

I have 6 of them, they are all in the same condition - as they sell, I will pull one off the pile! 

This listing is for ONE (1) tuner, bass side. Brass. Comes with mounting screws!
