Re: Museum seeks info on Stevens 22 Long Rifle
The rifle pictured may be a Stevens Favorite but it isn't the Model 1915, the last version before WW II. It's an earlier rifle. The falling block top profile is not squared off, a sure indicator of the 1915.
The number on the bottom tang, "677", might have meant something at some point. No factory records from this period exist. Serial numbers weren't required when this was made.
I don't know how you display this rifle or the context but from strictly a condition point of view, it needs a lot of help. Not a collector piece.
