I have a few bayonets for sale.
Left to right:
Epee French made Lebel 8 mm rifle bayonet
1873 Springfield trap door bayonet.
1873 Cadet rifle bayonet. Only 22,000 were produced if my source is accurate during the 20 years roughly that the rifles were in use.
This long last one in line is a tough one. I can't really 100% say what it is. I think it may be a variant of the 1866/ 71 Remington Rolling Block rifles bayonet.
Make an offer. More pictures available on request.
