Nice, a little Stevens Favorite.
Stevens made a number of falling or rolling block rifles starting in the 1800s and well into the 20th century. Some of the higher-end ones were very well thought of target rifles, while many were extremely popular as small game hunting or "boy's" rifles.
I have a 14 1/2 Little Scout that belonged to my Great Uncle when he was a kid.
These were made for the low pressure smokeless and semi-smokeless rounds that were available back then - do NOT shoot modern high velocity .22s in it or you'll loosen the block up in a few shots and the cases will start to rupture.
