Vintage Native American German Silver Bracelet

Can you decipher the letters "hidden" within the stamping of this old German silver cuff? Do you know why it's significant to us? The initials punched smack dab in the middle of the bracelet are "M.S". . . .Stands for Marti Struever . . .  or Martin Sheen or Master of Science or Medical Student or Mission Specialist (our favorite because we're all mission specialists) or Mississippi. You get the idea. Marti Struever sported this wonder woman cuff for a while, and she's ready to pass it on to you - only if you've got the right initials or best abbreviation.

It measures 1" high x 5 7/8" inside, with an opening of 1 1/8".
