Well, I picked it up Saturday.
It is a M23 Pigeon Grade XTR Lightweight with 25" barrels, choked IMP Mod and IMP Cyl, straight stock. Wood has very nice figuring and the metal surfaces are 100%.

I can't believe I got it for $1000 CDN.

I do need to get myself used to shooting targets and birds with the barrels beside each other rather than stacked.

Thanks to you all who answered my questions.!

Have a great hunting season, Y'all from southern Alberta, specifically Calgary!!!
