John: When I built mine, I was working for Robinson Firearms Mfg here in Prince George. At the time, there was a Hawken 'craze' and we were producing half stock percussions, full stocked flint rifles, a smaller 'hunter's rifle, and a ladies'/kits rifle, as well as the percussion Hawken pistol. If I recall, I believe the pistol components came from Pete Allen...perhaps he'll see this, and comment. Later, TOW marketed these parts sets, but Don Robinson's didn't deal with TOW. the company bought directly from the manufacturer - Green Mt., GRRW, Douglas, L & R, Allen. The stock for our pistol was duplicated from a prototype that I created myself, again, with only that one photo from John's book. We made all of our muzzle loading guns with Claro or Bastone walnut from suppliers in California and Oregon. It was always an exciting day when a create of stock blanks arrived.
The set trigger on my pistol is of my own manufacture. It has no backlash, which is a problem with the commercial offering. And it can be set so light that it will fire by it's own weight, if the muzzle is raised to vertical. That feature cost me a loss in a duelling match once. Since then, I stiffened it up to prevent that from recurring.
