If it's in good shooting condition you got a steal - What caliber? The reason I ask is they made an interpretation mistake on the originals and wound up boring the barrels to .530 caliber rather than the true .54 caliber of the original thus one needs to use a .520" or .525" ball which can be hard to find either pre-cast or moulds for that caliber - custom moulds are available from a couple of different makers at reasonable prices, such as Jeff Tanner and Larry Callahan.
The late John Baird (not Beard) along with gunsmith Ed Weber of Big Timber, MT did play an early role in getting these rifles started in production, but the company wound up cutting corners and not making the replica as originally Baird and Weber were led to believe would be built based on Ed's prototype of an original J & S Hawken in Montana. It's a convoluted story and enough said. Despite the differences the rifles were still of good to very good quality and many were excellent shooters.
