I cannot find a "Savage Model 59A" in any reference book - are you certain of the model number? There is a common Savage rifle, the Model 99A, which was chambered for .303, .30-30, or .300 Savage. The caliber markings will be on the barrel. If it is a .22 then it is almost always chambered for .22 Long Rifle. If it is chambered for .22 short, it will be marked as such. If in doubt, take the gun to a local gunsmith for a professional appraisal. The savage arms 59a is a bolt action 410 shotgun. Should have Stevens name on it above savage arms corporation.
There may have been a little difference in the grade of wood used and perhaps a little less care was taken in the fit and finish of the Stevens guns, but all parts should be completely interchangeable. Stevens was the economy line for the Savage Arms Corporation from about 1930 to 1990.
