The Lefever was mfg. in 1935.
The best that I can do is say that the Lefever Nitro special was made from 1921-1948.
Ithaca bought Lefever and that gun is the Lefever Nitro Special. My gun has a pointer on it and 2 ivory beads, one midway on barrel. Also my gun has a rosewood stock on it. Special made gun for somebody. Lefever gun had ducks flying over a marsh on receiver.
Your Lefever Nitro special will range in price from 300-450 dollars,based on your shotgun having between 60%-90% of its original finish remaining and a good set of bores.
If it is a double, remove barrel and you will see it along with serial #.
My brother can tell me when it was made. And he is never wrong.
The shotguns were manufactured by Ithaca from 1921 through 1947. Yours was manufactured in 1928.
Turn of the century.
Not clear on the question. There are no lever action double-barrel shotguns. There was a 'LeFever' in a few different variations, is that what you have? firstname.lastname@example.org
