This is not a 1 barrel. There are no makers marks other than the stamped. On the underside of the barrel. The finish is browned. The breech is finely fitted to the barrel. With this barrel you could potentially have all three calibers.

36 Caliber Green Mountain IBS (Thompson Center Interchangable Barrel System) Barrel in what appears to be new in unfired condition. I have included a bore scope picture of the inside of the barrel just up from the breech and there is no signs of any powder every being in this barrel, new and perfect. Measures 29″ long and 1″ between the flats. Very rare barrel in exceptional condition, shoots. 36 round balls or T/C Maxi Balls. Pictured installed in a Renegade Stock which is not included. Includes Ramrod, nipple and fiber optic sights. The pictures are not great and do not show the real condition of the barrel. I will try to post some better pictures in the next few days.
