Reconverted Flintlock

[Rudybolla]

I believe this rifle was originally the 1851 Pillar Breech percussion rifle, evolved from the earlier 1770s smoothbore flintlock.  Seems someone decided to reconvert to flintlock - why I bought it -but lock is incorrect.  I wonder if it would be possible to find a correct doglock flintlock to put on this?  I know the rifle is already a mongrel, but what the heck. Photos from auction house where I bought it.  They said it came from a French museum. Also attaching photo of similar short rifle.

I think you might need to do more research, it is hard to tell from the photos but I don't believe the lock in your bottom photo has many Norwegian/Danish parts.
