Dan LeFever was a Da Vinci class genius when it came to designing shotguns, but his business acumen was not on that level.
He set up a series of gun companies that made diverse models, including both sidelocks and boxlocks.
All were excellent.
One of his old companies was acquired by Ithaca. They traded on the name when they intro'd a entry level boxlock of their design and named it the LeFever Nitro Special.
A rather plain gun, it was built to the same tolerances as their upscale NID and was a lot of gun for the money.
The Nitros don't fit me, but I've done OK with a few lent to me for a couple shots. None had Damascus barrels and did have 2 3/4" chambers.
The last I recall around here had some mild corrosion issues(Probably used on MD ducks way back) and was mechanically tight. The tag was $450, IIRC.
As with all old shotguns, a lookover by a competent smith is a must have.
HTH....
