Congratulations & Compliments! I love seeing these early instruments still in service, treasured and appreciated.
* your tailpiece is like the one on #73-39, and a couple more instruments from about that same time... I suppose there may have been a couple options. I'm guessing the full 'moustache' must have been the next evolution of your type, but happy if not eager to be corrected.
