You sure can find some purdy stuff !!! The beautiful carving on the hilt and a pierced leather scabbard make this one of the best pieces I have seen. Do you think that a piece of the scabbard is missing or could it be that the leather has just shrank to the point that the end popped off when the blade was pushed in with to much force? As for the missing item on the throat piece, I would guess that it was some type of frog attachment like a short pin with a ball end. You already have my address so just let me know when to expect its arrival.
Congratulations on this wonderful addition to you collection.
