That is a very nice rifle. I picked up one like that at a pawn shop earlier this year, but my stock was more crudely cut. I found a stock for it at Liberty Tree Collectors. They had some engineer carbine ones online, I called them and they had one in stock for $150. I'll try to get some pics to post. I think I talked to the owner on the phone and he was very helpful.

Now I just need to find a shiney magazine (I'm not sure if it is chrome or stainless) because mine has the anchor markings on the bolt and rear sight. I think that means it's a navy model, but the magazine doesn't match.
