Ben's Loan in Renton. They usually have WWII and post-WWII surplus, which I pass by, but I couldn't let this one go.

Thanks SMLE Addict and jc5icon! I figured the post was a Hail Mary, but got way more information that I expected. I don't think a 'restoration' is in the cards - I think it looks gorgeous as is, but that rear site is an eyesore. Lines remind me of a Greener Lee Speed carbine I saw on an auction site once, or an RIC carbine (and thanks for the link to the photos Northof60 - if you had asked me to guess what it had originally looked like I wouldn't have come close). I got around to weighing it and it surprised me coming in at 9.6 pounds! I have had other .30 caliber carbines that were 7-ish pounds. Must be a remnant of its target pedigree?

So far as I can determine it has 5-groove rifling - honestly I keep losing count, but 7 seems excessive. I haven't dialed it in, but it groups well at the 50-yard range I can make up at my parents' house.

I am trying to post more photos of the proof marks, but must be doing something wrong. I will keep trying. I tried to dismantle it further, and managed to get the trigger assembly and magazine frame off, but the barrel band at the volley site is pinned and I am 'gun-shy' about tackling screws and pins willy-nilly. If anyone can walk me through getting the stock off, I will see what lies underneath.
