1950s Original Fender Pre-CBS Precision & Jazz Bass Reverse Tuner

Here's an original Pre-CBS Fender reverse wind bass tuner from, I believe, the 1950s.  I bought this tuner to replace the Hipshot drop-D tuner on a 1964 Fender Jazz Bass.  I'm selling it because I noticed that the tuning post is slightly taller than the other three original tuners from this bass.  My educated guess is that this is from the 50s Fender era.  It looks almost identical to the ones that I've seen on a 1955 and a 1959 Precisions.  The tuner works perfectly and is super solid.

I've included pics of it fitted to the bass for reference.  If you have a 50s (or early 60s perhaps) Fender Precision bass than this might be the right one for you. 

This sale is for the E-string tuner only.  Thanks for looking!
