Generally, depending on condition $100-$200 with the .410 gauge being slightly more valuable due to desirability. In areas of country where deer hunting with shotgun only is required many parents start young hunters with .410 gauge shotguns loaded with OOO buckshot so pump 410's are easy to sell in late summer/early fall. A 95-100% condition in original box Mod. 77 .410 would probably bring a premium. Manufactured 1955-71.
100 USD
If we are talking about a stevens model 77 shotgun?Then these were made by stevens between 1955-1971.
1930
Based on a response that I saw on another blog - SN's were not required until 1968. The Stevens 77D was manufactured from 1940 to 1960 and therefore may not have one.
NO
60-120 dollars,depending on overall condition and a good bore.
Stevens 12 ga, Model 77D, made before 1968 may not have a serial number. However, some do! If it has a serial number, it will be behind the trigger on the receiver side.
You can find a manual for a 16 gauge Stevens Model 77D shotgun by checking online resources like gun manuals websites, forums dedicated to firearms, or auction sites where vintage firearms are sold. Additionally, you might contact the manufacturer, Savage Arms, as they own the Stevens brand and may provide digital or printed manuals. Local gun shops or libraries may also have reference materials on older firearms.
These range in price from 60-140 dollars for a gun with between 60%-95% original finish remaining and a good bore.
There isn't one
I would start at the home page of savage firearms company,check customer service.Then you could look at E-bay and see if any have been reprinted.
