That rifle has an interesting history. It's release goaded Winchester into getting off their collective duffs, and getting the G 22 R into existence- later to become the Model 52.
I've got a pic of a 1932 model 19 in one of my books, and the peep on that one comes close to what's pictured here. Not an exact ringer, but close.
I'd be interested in how your rifle shoots with some modern quality target fodder. Nice lookin rifle to my eye, and nice wood, even if it is cracked.
