It appears that the hirshfanger bayonet is an oddity that even people here don't know about.
All I can say is that there are buyers on eBay who know about them because, once in a blue moon, one appears on eBay and ferocious bidding ensues.
I repeat, this is a hunting sword bayonet, not a fascine, not a pioneer sword, not a standard corps sidearm. Hirshfanger = a German hunting sword. Hirshfanger bayonet is subspecies of sword bayonet from the 19th century.
This is R.A.R.E.
I don't believe these things ever came out of England. I'd be surprised as heck if they were ever exported to South America. I think they are exclusively German/Scandinavian. (Collectors of German bayonets are most likely to know).
But go ahead, give me some information to the contrary. Make my day.
