What's the longest bayonet ever issued

[Richard Simmons]

I think it's either the sawback swiss model that Shuetz has or something for an Enfield.

is it more then 17"? because that's how long the blade of the MN M91/30 bayonet is....im not adding in the socket part...just the blade itself....if your talking about ANY bayonet issued regardless of century......I think the english plug bayonet is longer then 17" but I'm not absolutely sure on that.

[Schuetzenman]

Probably the Sword bayonet for the Zouave Rifle in the black powder age about the time of the Civil War. I think it's about 24 inches as a blade. Don't quote me I never measured one but they are long.
