I have a 16" barrel that will fit a 1911, I do not remember were I got it but have had it for 15 to 20 years. I have put it on my Colt Gold Cup series 70 and fired it and it worked fine. There are no markings on the barrel to indicate who made it.
I did a little checking and found this post on THR that may explain what it was from. http://www.thehighroad.org/showthread.php?t=373199
