Some correction should be made probably, russian NCOs used Mosin in scabbards, anyway they are really scarce to find on western market, majority of soldiers have it directly on rifles other way attached on barell in transportation position.
Personally never saw a german made ersatz scabbard for Lebel bayonet?, as this was 52cm long blade, similar german ersatz scabbard for similar long blade exist only for S98. probably, when for Lebels so for shortened blade.
Deutschland is normally stamp which was done on rifles, on bayonets its not extra well as the area is too small, visible that the stamp was doubble striked there and the die was prepared for a plain surface as the socket has too small diameter to see complete stamp there, only up to middle part is here visible.
