winchester 75 "milsurp"?

Took my first gun out of safe today for the first time in 20 yrs.
A model 75 target. Parkerized, stamped stock with number10 on forearm and under pistol grip with LK stamped onleft side of stock. Lyman peeps, parkerized. Serial#27188 This gun was purchased in New Haven at Winchester gun club when I was a 10 yr. old sub junior shooting 50 foot indoor. This gun cam from across the street at the factory on a wheeled rack to sell to club members for a modest sum.
Any info on these would be great>
Thanks, Art:sos:
