Their Model 75 rifle in 22 caliber.
The Stevens will accept whatever caliber designation is stamped on the side of the barrel.
Yes. Some are stamped Stevens by Savage Arms Co.
The model number is stamped on the right side of the receiver on many Stevens products.
Not much beyond what is stamped on the gun. Manufactured 1931-1941 by the Stevens division of Savage Arms in Chicopee, Mass.

My Springfield model 83 ( J Stevens) is stamped 22 Short, Long and Long Rifle on Barrel. If yours is as well, then yes, it would fire LR rounds.
Model 225 (usually stamped on the bottom of the reciever)
Mostly the name stamped on the side. Springfield was the economy version of the Stevens line, and Stevens was the economy version of Savage, so they may have a bit less care in the fit and finish or even used cheaper wood, but the parts should be 100% interchangeable.
I have one and it is a 7x57 caliber is stamped on the left side of the barrel.
This is probably an 1894 Favorite. Depending on condition, it is worth $125(poor) to $400 (excellent). A drawback is the scarcity of .25-caliber ammunition.
The Stevens 311 was marked as model 5000 from about 1920 to 1931, then 5100 until 1941. Most references just list the 311 as if it had the same model number for the entire production period.
