Anyone have any info on who made this barrel? Fits the mag nicely.

I guess it will remain a mystery to me. This is my first, and only mag. Got it this last summer. I changed the barrel, asa and feedneck. The barrel came with a very old bob long defiant I got probably 10yrs ago. I held on to the barrel, sold the BL. Never used the barrel until this past season. But damn I love how it looks on a mag.
