9422 bolt|Winchester .22 Rim Fire|Forum|Winchester Collector

I have a model 9422 and 9422M both made in 1976. 

I discovered this evening that much like a Model 70 bolt which has a serial number engraved on it, both of my guns have the last three numbers of the serial number etched on the bolt. 

I post this for no particular reason aside from the fact that I find this discovery interesting.
