Yes.
Please re-read the markings and repost. There is no such thing as a 22 short 410 long rifle.
Yes. The Savage Arms Company made over/under rifle/shotgun combination guns, notably the model 24 series. These were in 12, 20, and .410 shotgun, and rifles were 22 LR, 22 magnum, 22 Hornet, .223, 30-30, etc. Mdl 24S is a 20 guage shotgun under a .22LR rifle.
Your best bet is to find a gunsmith and ask for help.
It's a shotgun, not a rifle. Value for the single-barrel 'Newport' guns in .410 run about $75-$100. sales@countrygunsmith.net
100-400 USD
50-500 depending on specifics.
No such thing.
It is a shotgun
It is a SHOTGUN
Most of these guns wont have a serial number as they were made from 1938 to 1947, which was before they were required on long guns.
Need more information. I can find no reference to a Mossberg Model "410" rifle. Is it perhaps a .410 bore shotgun? Please describe your firearm more fully.
it is shotgun because the size of rifle is different than shotgun.
