I've inherited a small cache of swords, one of which seems to be an authentic Ames 1849 Rifleman's Knife.
I'm 95% convinced it's authentic.
Here are my questions:
Does this look authentic to you experts?
Is eBay the best place to auction it - or should I go with a high-end auction house (I'm guessing they'd watch eBay anyway)
I'm too scared to polish the blade, but should I polish the brass cross guard and scabbard points before selling?
Pictures are below. Any guidance is MOST appreciated!
with thanks,
Brooks
