yes Tim they do use that caliber but normaly as the Lee Enfield which takes a differnt fixing on the bayonet.
 In the hand one can see the leathers age though,  Fresh?   no chance!   
 
 
Its like loads of the Pre WW1 bayonet scabbards I see. You must as well? 
The bayonet is used but looked after, never even been sharpened.
