Help Please! Recently Found In Japan, Socket Bayonet And Scabbard

[Chonmage]

Hello,

 

I do know this is perhaps not what is usually posted here, but I can't figure it out myself and this board has always been helpful. 
I usually collect nihonto and fittings, but this recently surfaced. 

It has AR stamped on the leather of the scabbard. Due to rust I can't make out what the stamp on the bayonet itself is. Could be PO, but it's really hard to see.
I tried google and I've checked a lot of sites but I can't see any good match. I saw a cover of "Bayonets Of Japan written by Raymond C. LaBar", and it looks like it could be that one, but I don't own the book, nor do I know anyone who does. 

To the big question, what bayonet is this?

Leftover souvenir from Russo-Japanese War? 




Many thanks,

Anders

Anders, It looks like a bayonet for an Enfield rifle that was much used in the Boshin wars. What you read as PO willbe BO or 'Board of Ordnance'.

Hey 

 

Thanks for the really quick replies, Josh and Ian.

Ian, you hit the mark.

Found it on google now. The rifle you mentioned would be the M1853 3 Band Enfield Rifle I take it. 

Thank you very much for your help.

I do find it very interesting this piece could be from the Boshin wars.

I actually got it for free since the owner wanted to get rid of it. Will be needing to check with the police here, hopefully they will be in their right mind and not handle this as a WW2 type bayonet.
