Hi Fernando,
I havent really got more to add, but just wanted to say I keep getting drawn back to this piece simply because it has such outstanding charisma! This is a classic example of beautiful 18th century patination which contrasts perfectly with aged bone and the inset brass discs. In my mind there is little to compare to pieces like this, and I would leave it as is...aside from trying to repair that chipped bone grip.
I have to admit, I was thinking of the same thing as you on the ring, I guess thinking of those Central American dirks with a ring near the guard (in Levine, but dont have the reference at the moment).
Fernando, I think you are rapidly advancing on Rainhardts position in outstanding range in collecting!!!
Thank you so much for always so openly sharing your wonderful conquests!!
All the best,
Jim
