Hi Erik,
This is a Graflex XLSW. It's basically a roll film back slapped on the back of a large format lens. Most of the XL were rangefinders, but they made this little zone-focusing outfit too, because the rangefinder models were large. It looks complete. It should consist of a lens cone with focusing mount, a film back, and the wire sight. You could replace the wire site with a viewfinder if you wanted too. The 47mm super-angulon is relatively equal to 21mm on a 35mm outfit. I think the outfit is probably worth $400-600 in good working condition, but I haven't looked at prices lately. I'm selling it's cousin, a Brooks Veriwide, on eBay right now. It's the same lens with a 6x9 XL back. I'm hoping it'll go for around $1000. I think it'll bring a premium, because it's 6x9, and doesn't have the plastic focus mount that the XL line does, but you might be pleasantly surprised.
