Parts for such a gun have migrated to different companies and can't remember the exact dates these transfers were made.It originally was made in Morgan,Utah by the Browning Arms Co. from 1977 to 1980.Priced a bit higher than the TC guns being made then.One reason why I think they discontinued making them.IMO they are more traditional than the production line of the TC guns.All inventory of the JBMR was sold to Midway Arms,Inc. in Columbia Missouri in the early 1980's.Moved again and now parts are available from Deere Creek Products in Waldron,Indiana.I've called the number and it's current and in business.
I originally bought it in 1980 from a gun dealer camped at our local Cherrokee Ridgerunner club rendesvous.My first rendesvous.Usually getting 70 to 80 camps twice a year.Bought it at the spring event at the shooting range there where paper match shoots were held after selling 7 fur hats I made over the winter for $300.00.
I replaced as said earlier the original barrel [30" long with 1 twist in 66"]with a longer one [35" long with 1 twist in 72"] better suited yet for a patched round ball.Stocks were walnut with choices of steel or brass furniture.Excellent shooting rifle and my only big game rifle.It is rather heavy to tote all day long.Almost 9#'s.Should of maybe got a swamped tapered barrel to reduce weight,but they were more expensive too.
I had a friend do some scroll engraving on the lock as it comes with a plain lock.
Mostly hand made accoutraments used in bag.Short starter,nipple wrench,deer rawhide ball pouch,powder measurer,tear drop capper,and greased strip of pillow tick rolled up coming out of a slot on the side of a patch box made of osage.Prior to using the patch box I usually just tied a strip of greased pillow ticking onto the shooting pouch strap and a strip of long underwear for an in between shot spit patch wipe of the barrel and that worked fine too.Used to have a patch knife on strap too then but just use my belt knife nowadays.
