The Sierra Six looks like a ruger single six- or a colt peacemaker. Basically it looks like any pistol you would see on an old western movie. A good- low cost shooter....
A large revolver
Need to know iif its a revolver or semi-automatic and the caliber.
it look like a mountain
Look up 1894 Mannlicher pistol
if you are meaning as in a gun pistol you shouldn't of but it in this catergorie but a pistol looks like a L pointing the barrel to the sky which fires a range of bullets that match up to the pistol
Impossible to tell without a picture, serial number, caliber, barrel length, and type of action. Or look for the model:D
a rifle looks like a pistol but longer and fatter
Sierra means mountain range. Sierra also means a 'saw'. The whole thing means that the tops of the mountains look like the teeth of a saw
You can call Colt and give them the serial number or you can look it up in the Blue Book of Gun Values.
Go to Browning.com and look up the sn under customer service. Proofhouse.com also has sn tables.
I am not quit sure what you mean by "BALL?" I own several Crosman 38's, If you mean BB then the answer is it is not designed to shoot BB's. It fires a pellet that is either a .177 caliber or a .22 caliber depending on the particular model. If you look at the right side of the barrel it will say .177 or .22 cal to let you know what caliber the pistol is made to shoot. Do not use BB's in the pistol it will ruin the rifling in the barrel.
Like a Colt 25 auto
