Most likely Belgian
This is not possible except with an extended magazine and no plug, If you do not have an owner's manual for your shotgun, contact the manufacturer.
Remington did not produce a .410 side-by-side, except in the Parker. Please list ALL the markings on the gun, exactly as they are on the gun. sales@countrygunsmith.net
Remington. You could buy it out of Montgomery wards catalog in the 1920's
100 or so
There are no pool table markings except the foot spot dot. It is called the rack spot by some people.
Chickens can see just about as well as humans (except in the dark).
My hens are never left with a cockeral or rooster as I own only hens (except from my chicks) and the eggs are definitely safe! :)
Depends. In the US, a rifle or shotgun can be sent by US Mail. If crossing a state line, it must be sent to a DEALER in the home state of the person getting the gun. Handguns may NOT be mailed except by a dealer or manufacturer.
Riverside Arms was a tradename used by Stevens and later by Savage. Would help to know what other markings are on the gun.
The hen will lay eggs whether there is a rooster on site or not. In fact, commercial layers (the eggs in the grocery store) never, ever see a rooster. They live in a hen commune. You only add the rooster if you want to have chicks. If you keep the rooster just because he's pretty, he eats the food, bothers the hens and doesn't give you anything in return except something nice to look at.
A shotgun is a shotgun, regardless of what you do to it (except should its length go below certain limits, it will be reclassified as a pistol or handgun in some jurisdictions). If you saw some of it off, then it becomes a "sawn-off shotgun", pending the above restriction on length.
It shouldn't be anything except H2O, but there will always be impurities - which varies by manufacturer.
