Benjamin .22 identification

[Stinger177]

Hey all - I came across what is only labeled as a Benjamin .22. carbine. It appears to be a CO2 rifle, and what attracted me to it is the odd looking rear sight.

Can anyone identify this gun? If you notice in the pics below, the rear sight is screwed in from the side of the tube, and there is another mounting location further back toward the rear (circled in yellow).

The Benny is the lower one in the first pic. The other is an HW30S-X.

It's a 360-series CO2 gun (360, 362, 367 depending on caliber).  The rear sight is their "Bar-V" type, and the rearward cutout is for mounting their "Bar-O" peep sight.

Thanks.

Is it rare? What do you think one in working order should be worth?
