if it is a Montreal it will have been made in the seventies, value approx 500 pounds or 750 Us,,
The maker was Gamba flli (Gamaba Brothers) made in the city of Gardone, Italy. Yours was made sometime between 1946 when G. Gamba started production, and 1967, when G. Gamba sold his tooling to his brother, Renato.....and the company became Renato Gamba. These were reported to be well made high quality shotguns, but there are so few sales in the US that I cannot find comparable sales to give you a current value- sorry. You can get the best answer by taking your (unloaded) shotgun to a gun show near you, and let some of the dealers and collectors take a hands-on look at it. Condition will drive the value of most guns. There is not a high collector's market for these, but they are considered a quality firearm. Later model Gamba's are offered for sale for several thousand US $$$, depending on the model.
A Charles Daly Diamond Skeet with 60% of it,s original finish is worth 775.00 dollars.A finer example with up to 80% will bring 1,000 dollars on todays market.
$125
This savage shotgun is selling for between 150-300 dollars depending on the condition of the wood and metal finish remaining.

Your Winchester model 12 skeet shotgun in 28 gauge is a very rare bird!!If your shotgun has a 60%original finish to it.The price could easily be 3,900 dollars to 4500 dollars.If your shotgun has more original finish to it we could be talking 6,000 dollars and up.I would have your shotgun appraised by a member of the Winchester collectors assoc.or a Person who is qualified to give you a correct evaluation of your shotgun.Good luck and enjoy that wonderful rare Winchester shotgun.By the way if your length of pull is 14 inches,then this is a pre-war shotgun.(1933-1941)The Winchester model 12 skeet version was made from 1933-1976.
It's a solid $850 shotgun, I don't think you can find one for less.
50-290 usd
50-150 USD
Too many variables to answer your question. Is it a field, Skeet, Trap? Condition, barrel choke and quality of wood make a lot of difference to the value of the gun. Need more info..........
The company is worth millions.
I don't know, but have one just like it. over/under silver receiver with engraving, checker stock, and have no idea on it's value. Looks like it's a pretty nice gun.
