Gibson Master Tune Vibrola Tremolo

For sale a rare Gibson OEM Bridge manufactured by Schaller in Germany. This was for a guitar project that will never come into fruition so I must part with it.  Very little information out there for this but some flying V's and Junior LP Invaders came with these originally. I believe it was only a run of two years that those guitars had this equipped. Any questions please ask. All sales are final.
