I bought this rifle at the Dallas gun show around 1980. I thought it was a Stevens but didn't know which model and thought it was a put together "Frankenstein" rifle for Texas Hill Country (settled by Germans in the 1840s I think) for Schuetzen matches . Several years ago I gave it to my son and it's his favorite rifle and shoots it very well. The other day I did some research and determined it is a Stevens and the rifle was built around a 44 1/2 falling block. I believed I read the 44 1/2 was manufactured from 1902-1915 or 1916 and Stevens used this action to build rifles in various calibers. I read that only about 13,000 were made. I assume not many were made in .22lr caliber? I will call Savage and see if anyone has any history on this rifle-I will be surprised if they do. I have pics below and I'm interested if any of the pieces of the rifle appear not to be original. I know the Redfield sights are not original, three of the stock screws don't appear to be original. I measured the barrel to be 25 5/8". I suspect this is shorter than when manufactured and was cut for better balance and probably at the time of installing the Redfield sights.
The barrel exterior is shiney and I assume the barrel was initially blued and has worn off? This is a heavy bull barrel. The butt plate is plastic and states "Bishop".  It shoots great, no rust and the wood is in good condition. Any information or thoughts much appreciated.

One more time.  Apparently I can only post one pic at a time and no option for thumbnail pic.

Very cool lever and double set triggers. Too bad the barrel was shortened. Stock is obviously aftermarket, post-WWII era since it's a Bishop stock. Don't waste your breath contacting Savage. Guarantee you nobody who'll answer the phone would have a clue as to what you're talking about, and the Stevens factory records have been gone for a hundred years. Post the serial number and folks here can give you a rough ballpark idea as to when the action was made.

Your rifle being a 44 action with double set triggers was most likely made pre 1903. The barrel being full round is also most likely not the original barrel. Any markings on the barrel? Does it have the extractor in the center or the side commonly called a 7 o'clock extractor? The serial number range would help narrow it down as said. 
Nice rifle but not original.
