Raygun,
after some digging through my stacks of stuff, I finally found that stock with that heros name on it.
D. A. Fowler and then there is also Gouburn scratched under the name.
The number on the stock iron is pretty banged up but I think that I read 9283a
I bought this stock and the attaching leather, cup and straps over Ebay from an Australian guy so I believe that this has a pretty good chance of being a true Aussie war trophy. The bidding on Ebay was pretty brisk. I'll have to go over my notes to see if the holster also came with it. That would give us an approximate date. But I do not think it did. I think that I remember working the seller over pretty hard in an effort to get the holster or any other rig from Australia. We had some pretty nice conversations over the computer, but nothing ever came of it.
