Yes Gaspare, as far as i know there is only those two type of rings as you mentioned made by Fahrner. As i collect Fahrner jewelry made during the TR i have both style rings, cufflinks, stickpin and pendant made by Fahrner and then Fahrner advert in shape of poster where all of these jewelry pieces are shown. Now is it possible that Fahrner made some private purchase ring for some officer or high ranking member and that is out there that we don’t know about i wouldn’t be surprised. Fahrner was a great jewelry company, they made some nice pieces of jewelry!
