I don't know enough to comment, but I do have a question.
Does the lock appear to be original to this gun?
The lock on the Haga attributed rifle appears to be a much later lock than I would have expected on a rifle predating 1796, the year of Haga's death.
I'm rather curious about the sharp transition from the rear of the lock and sideplate panels as well. The photos don't clearly show if that transition area contains deeply sculpted beavertails, or just a sharp transition to the wrist.
I don't intend to question the Haga attribution, just curious.
Nice gun too. Gotta love those Womelsdorf-Reading School rifles.
Thanks, God Bless, and Merry Christmas.
