Sounds like a great buy!
My Father has a 61 22 Mag that is his favorite by far. He refuses to scope it even though it is "grooved." It is no wonder that no one can make anything similar nowadays in a mainstream production rimfire... too much machining, engineering, and attention to detail. It would have to be a "custom" at custom prices. I would rather have the 22LR version like yours but if given the choice would take the grooved receiver for my personal interests. Those early Winchesters are in a class of their own, though.
IMHO, I would not let that redhead from the bank know you own that!
