What rifle is this?

[Giant]

Hello!
And greetings from Finland.
I got this old rifle from my old relative. And now I´m intrested that what is it.
If someone on this forum could tell me something about it, I would be wery thankful.
Barrel hole is 20mm. Saddly stock is in very bad shape, but flintlock works very well.
In the atop of the barrel is one mark: "N31". And inside of the flinlock is two marks wich are possibly: "CÄ" and "HC".

Very difficult to say.  An early european military musket (1700s) but where from is difficult to say.  The shape makes me think that it is Germanic but further than that I can't say.

It is probably north European - German or Danish - but probably produced later than 1780. I can not recall any Danish having this lock and barrel, so...

I think that it could be Swedish our Russian.

I know very little about Russian small-arms, except that they had a hoard of German gunsmiths in the late 1700's. The lock plate looks a little like a Potzdammer lock plates. What I am very sure of, is that this is not a Swedish rifle.

Thank you Trond from information.
Because this rifle interests me a lott, could you tell couple reasons why that cannot be Swedish?

Easy: All Swedish long-guns from this period had dog locks.
