Thanks for the leads guys. Still haven't found any concrete information. I was told that this was a davidson's special edition run, but still haven't verified it yet. The gun was near mint when I got it with just a light ring around the 357 cylinder and I ran a box of corbons through it. After posting here I dug it back out of the safe and attached the 38 super and all looked great. I also attached the 9 mm and actually shot it. Ran 3 cylinders though of rem 115's and it shot pretty much the same as the 357 at 25 yds which suprised me. I wasn't sure what difference the .355 vs the .357 slugs would do, but I was pretty satisfied. My cylinder marks went from almost nonexistant to very light, but I plan on keeping the gun anyway, so why not shoot it. (Need 38 super rounds now). I didn't mount the other 357 mag because it is pretty much flawless. Anyway, a big THANKS AGAIN for all the input.
