Hi Fernando,
A great addition to your collection. Where do you put the ball and powder

. ??? It is just as well that Jasper has nailed it as I cannot find a similar example of the type anywhere and as you've no doubt gathered I've not seen one before. Are you going to do anything about the urn pommel and the ivory grip or are you going to put them down to period repairs and leave it like that? Great and unusual piece.
My Regards,
Norman.
