Yustas, it is seldom that a standard type military sword is of the 'rare' catagory, and frankly it is a matter of perspective. I have seen issue type sabres of which only a set number were made, and sometimes most of the issued swords did not survive obsolescence if they did not end up with militia, yeomanry or ersatz units. Still, rarity is a complex term, are you referring to the style tip or sword type overall?
I'll check Wagner, Bezdek and some other references shortly and get back to you......unless of course there might be someone else out there reading this, and might have information
Best regards,
Jim
