I'm looking at an alleged Bresien blank of .50 caliber, 23" twist and about 36" in length. No markings. It has a 5 groove "Remington Pattern" for rifling.  I'm interested in any information that would lend or deny credence to its provenance. 

Thanks,

Dan

Yes, "Uncle Ken" is still with us however his health is not very well. He sold his barrel making business and most of the equipment some years ago. I have been fortunate enough to have owned several Ken Bresien made rifles and barrels. As far as I know Ken always marked his barrels after machining was completed. Those that he blued were marked at the completion of the barrel preparation.  Marks were all the same as far as I know and have seen. "Ken Bresien  Warsaw N.Y I still have three barrels. Two muzzle-loaders and one .40 cal. on a Win. Hi-Wall. 
Wish I still had all the ones I sold!!! Round-Ball Bench rifles and Slug-Guns.

The barrel you have question about would be hard to verify if it is not riffled and is just a blank. It's one of those things that a good story can be spun around, especially with out stamping.   
Sluggunner may be able to shed some more light on this topic and Ken's health.
. I don't know what the seller is asking but it might be a bargain even without proof.  Let us know how it turns out.    4227
