RJB:
The average length of the St.Etienne Type D French trade gun (Fusil de traite) barrel was 52 inches , some substantially longer. Mine has the one-size-fits-all barrel length of 42 inches. If we go to the trouble of trying to make things period correct I for one would like the barrel lengths to be period correct too. Just saying!
There are only a couple of barrel maker's that will go past 48" long. For the most part they are back logged for years.
If Jim Kibler would add such HC fowler lengths/bore sizes/breech diameters/barrel wall thicknesses/octagon-round profiles/round profiles as I, yourself, and others are asking for into his inventory/CAD computer design program; then he would not necessarily have to keep them in stock for immediate sale/delivery.
My suggestion would be that the specific barrels for the various, and myriad, smoothbore civilian, military and quasi-military, fowlers and muskets that we would all like to recreate could be offered/fabricated on a semi-annual basis. The Kiblers could take orders for such custom offerings with a REFUNDABLE/NON-REFUNDABLE DEPOSIT of say $50.00 to discourage people from wasting their time. Deposit to be refundable up to say 90 days prior to the date of delivery. This would allow them time to order barrel steel, schedule time for fabrication/packing/shipping. After the 90 day mark, NO REFUND OF THE DEPOSIT. Unless, of course, there was a serious mitigating reason, such as death, injury, or illness.
This would also allow them to gauge the interest in such offerings, and let them decide if it was sound business practice to offer such a service.
Most of the custom m-l barrel maker's seem to be in their '60's, '70's, and '80's. Bobby Hoyt, Charlie Burton, Howard Kelley, Ed Rayl. No one seems to be stepping up to take their place.
Same thing for The Rifle Shoppe. What an amazing resource!!!!
What an amazing PAIN IN THE A$$. One person orders, and gets their parts/kit in a single week. The next person orders, and it takes 18 months for things to arrive. Many lock kits have sub-standard parts in them. The phone often goes unanswered.
What happens when the principals retire, or die? Seems like a perfect candidate for a modern CNC update.
I will be willing to take whatever Jim and Katherine can offer our community. We just need 20 more folks in their late '20's, early '30's to step in and bring CNC machining to other aspects of traditional muzzleloading
