I'm another southpaw, approximately 1 in 12 shooters are left handers, but no commercial company caters for us at all. Usually it's an expensive conversion on a standard rifle that has to convert it to being a lefty's gun. I don't think you'd have any problem selling that RB as a left handed .22.

Ya def'nit'ly done good, Don.

Looks good. You definitely have not lost the touch. That inside curve where the cheek piece rolls over the comb is not easy to do.

Wow, I hope mine turns out something like that!
These are great looking pictures and will help me a lot, thanks!
What tools do you use, and do you have any "cast" on the stock?   
As a lefty I think I need some cast; I'll probably have that thing looking like a laid over hockey stick, heh.

'Cast' refers to the slight bending of the comb line.  'Cast off' is normally for a right handed shooter and is usually around 3/8"  'Cast on' would be for a left-hander.  It's measured but running a long straight edge from the front sight through the 'V' notch on the rear sight (or the center of the hammer) out to the butt of the stock.  Then you measure the center of the butt in fractions of a inch either to the left or the right of the center line to get your 'cast'.  If there isn't any, you don't have any.
