Vintage Navajo Hand Stamped Cuff signed "MWT" 25.5g (1201)

Interesting vintage Sterling cuff with hand-stamping both inside and out. It is signed "MWT". I have not been able to find the artist's name. I assume it is Navajo. It appears quite old due to the wear of the outer stamping. It has good weight at 25.5grams and is 1/8" thick. Measurement inside end to end is 6" with a 1" gap for size 7, with very little flex.
