Bayonet question/ID

[LongWalker]

So I'm digging through my box marked "MISC STUFF" trying to find a buttstock for a Savage 99.  No joy with that, but I found a bayonet I don't recall the purpose for.   Any bayonet fans here who might be able to help me ID it?

Frog is leather, with a large-headed brass rivet holding the two pieces together.  Scabbard is steel, with a really cool interlocking joint (I probably picked it up just to study the join, as that is some neat work).  Bayonet mount has a locking ring; eyeballing my calipers, I make it about .745" ID at the breech end of the tube, maybe .730 or so at the muzzle end of the tube.  Blade is triangular, surcharged US on the broad flat. 

Not sure what it was originally for, figured I better see if anyone has any ideas before I abuse it or lose it again. 

(I know, worthless without pictures.  Trying to remember where my camera is, and figure out a place to post the pics that ain't gonna hold the pictures for ransom someday.)

Thanks,
Jim

Sounds kinda like a militia Trapdoor bayonet and scabbard. Some of them had a plain brass rosette without any state or federal marking

I suspect you're right, but I don't have a trapdoor around to test it on.  :Maybe if I can sneak away from work this week, I can test-fit it on one at the local gun-pusher's shop. 

(Found the camera, but work went pear-shaped today so I haven't had a chance to shoot pics.  Working on it.)

thanks for the tip, Pitspitr!  I did some test-fits.  The bayonet rattles on a 45-70 trapdoor (tried it on several; for the curious, average muzzle diameter was about .728").  It fit very nicely on a 50-70 trapdoor with an "1870"-marked breechblock.  <sigh> Having no use for it, I'll get it listed in the Classified someday.

More importantly, I FOUND MY SAVAGE BUTTSTOCK!!!!!!!

How can you say you have no use for it? It's obviously sufficient justification to get a 50-70 trapdoor! Maybe the one you tried it on?

[LongWalker]

Don't want an issue trapdoor 50-70; don't like the twist rate of the barrel.  Maybe someday I'll part together a period-styled sporter, but the twist rate will be better suited to a mid-weight hunting bullet.   Besides, the only use I've ever had for a bayonet was to to cut it down and make a candlestick holder!

As luck would have it I have a 50 70 trapdoor without benefit of a bayonet.  What would you take for it?

Bat, I'll getcha a PM sent here in a couple minutes.
