I love how people fail to throughly read my OP.
I have zero desire to have anyone build me an inline muzzleloading pistol.
What I do desire is for someone to build me an ambidextrous, flintlock, sidelock, long-barreled, muzzleloading, big game, hunting pistol whose stock would have a secondary, short, pistol grip that would extend downwards/rearwards from the underside of the forearm to allow for a more secure two-handed grip.
This is something that I require not simply desire. My osteoarthritis has caused a significant strength loss in both shoulders/arms over the past two years. As a result, I have been advised by my Primary Care Physician to limit as many stresses to my shoulders as is possible. This means either giving up all hopes of hunting, or finding a new, different way to approach how I conceive of hunting.
As far as Doc White is concerned, he is about to turn 85 years old, his queue is full, he has limited use of his right hand/arm due to a rotator cuff injury several years ago, and I have witnessed a noticeable decline in his inletting skills since the injury, on those guns that I have seen images of posted online.
All I want from Doc White at this point in time is to borrow the concept of his two-handed, inline, Javelina hunting pistol, and apply the concept to a flintlock, sidelock hunting pistol.
If such a pistol offends any of the purist builders here at ALR, tough!!!
Is such a flintlock hunting pistol traditional? Absolutely NOT!!
Would such a two-handed, flintlock, hunting pistol allow me to resume hunting at the age of 68? Absolutely YES!!!
Would such a hunting pistol allow me to hunt into my 70's, perhaps into my 80's? Possibly. And, right now, that's the best I can think of. I do not wish to try handgun hunting with any kind of heavy recoiling centerfire handgun. A two-handed, sling-assisted, muzzleloading pistol of .62 caliber, with interchangeable rifled & smoothbore barrels is what 1.5 years of spitballing & conceptual thinking has brought me to.
If someone here wants to help me, fine. If you don't want to help me, so be it.
