Thanks Dan, this is the finest gun that I've got, so far; when I opened the box and examined the barrel, I was so happy about the quality and condition of it that the damaged axle didn't even really phase me. The person that owned this gun must have just admired it on a shelf, because theres not so much as a scratch on it, and the bore is as pristine and polished as the outside of the tube. The only thing that bothered me was that the seller (who said he picked it up at an estate sale) had polished all the patina away.
The barrel's 16 ½'' OAL and it has a .91 caliber bore with an angled 3/32 vent.
Zulu,
You may be right about the reason for making the axle the way 'Valley Cannon Works" made them; I'm not arguing against your judgement, but I was thinking that the reason might also have had something to do with a surer way of making certain that the four trucks sat even on a flat surface. I've only made two carriages, both naval four truck mounts, and on both builds I've had a little difficulty with "rocking horse syndrome".
I had to perfom corrective emergency surgery on both carriages, and hide the scars as best I could.
Your memory is in fine working order, Douglas; I did remember jeeper's purpleheart mortar bed, because the beauty of that wood really struck me at the time, and I don't think I'd ever heard of the wood before that.
Purpleheart would be another fine candidate for the choice of carriage wood. I've also recently learned about an incredible African wood called "Pink Ivory", and while I wouldn't like the pink shade for a carriage, it can also sometimes have a beautiful red hue.
