A while back I bought a Super 16 .45/70 barrel that showed no evidence of ever being mounted to a frame, not a mark anywhere. I didn't notice when I bought the barrel but the dovetail locks were missing and on close inspection the dovetails don't look like they ever had anything installed. I have had a handful of .45/70 barrels over the years including a couple of Super 16s as far as I can remember they all had a factory "Muzzle Tamer" brake. This new barrel doesn't have a brake. How common are these barrels? I planned on shooting it but if it's a valuable collectors item I would rather a collector have it and I'll come up with something else to shoot.

Thanks in advance!
