The sling ring is also called a saddle ring sling and can be used with something like the sling at the link below. I'm no expert, but I just got a 94 from my father-in-law and was poking around the interwebs asking this very question.

Value is figured by condition,markings,and history of the gun.(How do you know it was used by the militia?)etc.
Your question has used the serial number of your Winchester,not the Model number.Please include a description of your Winchester along with the model number,and the serial number to get a answer about your Winchester.
It was a Winchester model 1876.

How much does a used Winchester model 1300 excellent condition with pistol grips and a side saddle go for?
A sling is typically used to support and immobilize the arm. When no sling is available a triangular bandage may serve as a sling..
This bolt is the same one used in the Winchester model 57, 69 and 75 rifles.
I would check your model number?The Winchester model 1897 was a shotgun made by Winchester,while the 32-20 caliber is a rifle cartridge that was used in the model 1894 Winchester lever action rifle and other models,but never in the model 1897 shotgun.
