A couple of years ago I was brought a bunch of long guns (4 rifles and one shotgun) to sell for a friend of my Fathers. Among them was this Winchester model 74 Semi-Automatic .22 Rifle.
I ended up buying them all (it's a sickness, I know...). Among them was this Winchester.
Disassembly is facilitated by removing the bolt stop at the rear of the receiver (push it from right to left). The stock is made from straight grain American Walnut.
The design of the rifle intrigued me, enough so that I decided to do some research on the history of this little semi-auto.
The manufacturing of this model started in 1939 and ended in 1955, with manufacturing taking a hiatus in 1943 due to the war. Although some were built during the war and shipped to England on a Lend-Lease program as training rifles.
This particular gun dates to the second year of manufacturing: 1940.
Incidentally this was also when the .22 Long Rifle chambering was 1st offered.
The 1939 models were .22 Short only, the .22 Short chambering was dropped in 1952.
Later versions came with a grooved receiver for mounting a scope with 11mm clamps
The list below shows the build dates by serial number
