What kind of information?
Call the maker or find books published about the maker.
Realistically, you can't.
There isn't enough information to answer this question. Serial numbers are not unique to one firearm - they may not even be unique to one firearm from a single manufacturer. Several guns could have that serial number.
If you are refering to just the model 1894, a serial number search turned up the following information. Serial number 15,579 was made in 1894. Serial 15,580 was made in 1895.
Not possible. There is more than one gun with the same serial number, some guns were made with NO serial numbers, and data does not exist to translate SN to make/model.
Yes, as long as he knows the serial number.

Most F&Ws that HAD a serial number had it stamped on the butt- and stamped on the rear of the cylinder. LEGALLY, the one on the butt is the serial number. Many older guns did not have serial numbers, especially lower cost guns.
That is impossible to answer. If we knew the manufacturer and model, the serial number MIGHT be useful to find additional information, but you cannot find the manufacturer by the serial number. A few manufactures have used a single serial number sequence through many models, but most have began each model with serial number 1, so the same number may appear on hundreds of guns from the same manufacturer. Before serial numbers were required, some makers used "block numbers" which would re-start at 1 each time it reached 1000 or 10000, so the same number could appear on several identical guns. Your gun can probably be identified if you will list all the other things written on it.
Not certain of your question. Not all guns HAVE a serial number. They were not required on US rifles and shotguns until the 1968 Gun Control Act.
If sn data has been published you can find out when it was made/shipped and sometimes to who and with what features.
Your gun was manufactured in 1908. You can find such information on many handguns (the notable exception being S&W) at proofhouse.com BTW, in the name of privacy, "X" out the last 3 digits of a guns serial number. The first 3 will do.
