m/1815-20 Sweeden Sword bayonet bayonet to Jämtlands fältjägare repro or original?

[Ljus]

Hi!
As I know, the blades of Swedish M1770 cavalry palasch was used for produce ~ 800 similar bayonets.
As I know for sure that price of palasch M1770 much more less then this bayonet...
That's why unscrupulous dillers may have too great temptation to modify original M1770 cavalry palaschs in to
m/1815-20 bayonets in 20, 21 century...
What do you think about originality of fragile lockin system on this bayonet ?
Does it original? Or may be modern falsification for price enlargement?






Thanks for any replies!
