We'd have to start by figuring out what make and model it is. What markings are on the gun? sales@countrygunsmith.net
on a single shot barrel you must remove the barrel and look at the flat side underneath the chamber to see the choke stamping.
Provide a detailed description including gauge, barrel length, all markings, overall condition and finish.
Impossible to answer without a detailed description of all markings.
Are there any other markings on the receiver or barrel? I have several listings for "Price" shotguns made by W.H. Davenport Arms and J. Stevens Arms & Tool Co, but nothing with Mo N or No N.
Probably made at the turn of the century.

Can't be answered without a detailed description of all markings, finish, condition, etc..
I can't find a Stevens 851 listed in the Blue Book or Standard Catalog. To find out more, see if you can get all the markings on the gun and consider the action (single shot, double barrel, bolt action, etc).
That patent date identifies a Stevens single shot.
I assume your single action is pre-war ? If so, then made about 1907. As to the caliber, check markings on barrel. that should give the caliber.......
