Keith - while you're posting that data, if you don't mind, let me ask about our own, old Winchester. It is a Winchester 22 L. or L.R., Model 190, s/n B2026713. It has a Sears scope 4x15 Coated Image Moving, Model #53988. (scope's probably not mil spec, eh?)
Note you can email Winchester for owners manuals via their web site at
http://www.winchester-guns.com/ , and check in their FAQ's, towards the bottom of the page. [I haven't heard back yet on my recent request.]
Also, there is a kind fellow at
http://members.tripod.com/~stock4broker/Firearms.html who is doing firearms research for folks, but I'm reluctant to query him about this particular rifle.
Anyone familiar with my rifle too? Thanks.
Keith, good luck.
