I have an 1840 French "stalking gun", with the right barrel being rifled, about .35 caliber. The left barrel is smoothbore, about 16 gauge.
The right trigger is a set trigger, push it forward to "set", then light pressure will cause the gun to fire. The left has a simple, single-action trigger.
Beautiful gun, nicely engraved, fantastic wood.
But that right lock has a well-used half-**** that simply will not hold; it is too worn.
And Hamfisted Codger Craig has not the expertise to re-stone that half-**** notch in the tumbler. I suspect that the sear on the hammer could use some help as well. The lock is equipped with a fly - and all interior parts are polished to rival stainless steel.
I'll get it done one of these days, if for no other reason than to take TWO firearms to the range: I have a gorgeous ENGLISH double to match the French one. The English is a straight-forward 15-bore. Both arms are about equal in fit and finish. I have been practicing my French - my English cussing is outstanding, but need to brush up on the French. "Alors" will just not be adequate for something going amiss on the Frenchie.
