10-100 USD or so
FIC was an importer, not a manufacturer.
100 USD
FIC did not make firearms, they imported them. No way to answer without a detailed description of all markings, barrel length, caliber, stock, sights, finish, condition, etc..
Blue Book of Gun Values
http://www.cornellpubs.com/Templates2/FI%201969.htm Look at the table of contents and see if you can find your rifle. Firearms International was an importer, not a manufacturer. They imported Sako, FN, Garcia, LaSalle, AYA, Rossi, Star, Astra, etc.
Firearms International was an importer, now out of business I believe. It is unlikely that they would have actually marked the gun with their name before these markings were required in 1968. There are probably other markings that may identify the actual manufacturer. Double Action refers to a revolver mechanism and I have no idea what you mean by a doubleaction trigger on a rifle.
DO NOT DO THIS!!!!!!!!!!!!!!!!!!!!
I suspect this is a foreign firearm imported by that company. Unless it is some special target rifle, a 22 single shot is probably only going to bring $75 to $100 in used condition.
If you're talking about firearms, caliber refers to the diameter of the bullet or the bore size of of the gun.
yes they did
there are dozens of calibers from .17 to .70
Need more information. Value will depend upon original maker (F.I.E. was the importer) and condition of the firearm.
