The history of the gun can be found in the very extensive and detailed DGJ article by Keith Kearcher along with lots of photos. I don't remember if the article alludes to the missing barrels or not. If I'm not mistaken it is vol. 6, issue 3 (1995). I don't have that issue so if someone would be kind enough to look up that article and post the gun's serial number here I would appreciate it. I had the serial number but it would literally take hours for me to find it. I have a nice set of Titanic ejector 20 ga. barrels . . . who knows, they might be the ones . . .
