It's a shotgun, not a rifle. Value for the single-barrel 'Newport' guns in .410 run about $75-$100. sales@countrygunsmith.net

Without knowing who made it and the type of action, no. Even then, there may not be any published data.
None published. Try shotgun collectors.
You have to state whether it is a handgun, rifle, or shotgun and then whether it is a bolt action, semi-automatic, single action, double action or pump action.
Correction.... It is a single barrel, pump action
70-100 years.
