Vintage DACOR TENUE diving mask: tempered glass w/ stainless steel bezel, extras

Description

Vintage DACOR TINUE diving mask: tempered glass w/ stainless steel bezel.  We are getting ready to sell our home and move to a smaller place soon.  I uncovered a large box that held some of my old toys and found Dacor mask.  It was in the plastic storage case that it always lived in and remains in what appears to be nearly new condition. It was very well cared for when I was diving and it did travel with me a fair amount.
This was a very high quality mask in its day. I bought it for a trip to the Sea of Cortez and as I recall, it was a very expensive purchase at the time.
There are two extra straps with it and they are in unused condition and still completely pliable. I dry tested this mask and cleaned it thoroughly making sure the purge valve still works properly.  It has been in storage here and untouched for a long time but appears to be fully functional. No guarantees.
