70-100 years
I HAD AN OLD GUN SIMILAR TO THE ONE YOU ARE TALKING ABOUT AND IT WAS MANUFACTURED BY A COMPANY CALLED SHAPLEIGH IF MY MEMOERY SERVES ME CORRECT Is it a windmill or possibly the Perone, an oblisk similar to the Washington Monument? That would be a Belgian proofmark. Shapleigh was a hardware wholesale/retail business that had its tradename guns manufactured by several manufacturers. "Nitro" would indicate the gun could safely fire the smokeless or white powder which was developed around 1900.
The best that I can do is say that the Lefever Nitro special was made from 1921-1948.
HAVE IT CHECKED OVER BY A GUNSMITH FIRST!!!!!!!!!!!! It is an old shotgun.
The Lefever was mfg. in 1935.
Known tradename used by Shapleigh Hardware. The guns were made by several different manufacturers, although your double is probably a Crescent. 1900-1930.

Your shotgun was manufactured in 1923, by Ithica Guns which took over the Lefever brand when they acquired the corporation in 1916.
