Ross, according to the date code in your first picture (4F in a circle), your gun was made in 1954. In looking at your pictures, I believe the barrel and the stock on your gun have been shortened. The stock should have a 14" length of pull and the barrel should be either 26 or 28 inches in length. An accurate way to determine if the stock has been cut is to remove the butt plate and look for the assembly letters/numbers that are stamped into the wood under the plate. If the stock has not been replaced, these L/N's will match. Try measuring the muzzle. On a standard 26" barrel the diameter is .54". If it is thicker than that, most likely it has been cut. Also, compare the L/N's on the inside of the barrel in front of the lug. These should match the stock and the inside of the frame, if the gun is original. There is always a chance that an aftermarket barrel was fitted to the gun. I have Savage catalogs from 1937 past the dates these guns were discontinued. There is no information about a "Youth Model". However, that is not to say there "never was one". I have in my collection several guns not listed in the Savage catalogs. It would be helpful if you could furnish pictures of the stock under the plate, and under the barrel in front of the lug, and on the inside of the frame on top of the left rail. I hope this will help some. Welcome to the forum and thanks for sharing your gun with us!
