There's a guy who has a booth at most the local gunshows in the Louisville area and he has several new and used DW porkchop barrels
I'll try and get his contact info for ya!
The next show is January 29th-30th
I also saw a Sentinial High Standard at the last gun show and they wanted $550 for it, Needless to say they packed it up and it'll be around for a while, The owner said it was RARE!!
Also Biff's GunWorld in Valley Station Kentucky also has a huge box full of Dan Wesson Barrels Cranes cylinders etc.
I haven't been around in a while but am still lovin my Dan Wesson 15-2
Here's a pic of my newest addition to the family a S&W M642 and my Ruger SPNY and My HardChromed HK P7M8
