Awesome, ThanksI remember the Johnathan Browning Mountain Rifle which was Browning Arms' attempt to capture part of the growing muzzle loading market in the 1970/80s when many states began introducing ML deer hunting seasons. They were well made guns and more so of an exacting copy of a Hawken rifle than the Thompson Centers ever were. They were also pricier and a tad heavier too which is probably why you see way more TCs out there than the JBMR. IMHO I'd rate them as a very well made commercially produced rifle and depending on condition they would fetch maybe $300 to$800.... possibly be even more. There's a lot of info on them if you do a search. Below is a 1980 ad...
