The best that I can do is say that the Lefever Nitro special was made from 1921-1948.
1927
On a Lefever Nitro Special shotgun, the serial number is typically found on the underside of the receiver, near the trigger guard. It may also be located on the barrel, often on the side or the top, depending on the specific model. If you’re having trouble finding it, checking the owner's manual or consulting a gunsmith may help.
It is found under the breach below the barrel
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.
This was apparently prior to the acquisition of Lefever by Ithaca, since it appears that the first Ithaca Lefever serial numbers contain 6 digits (Lefever Nitro Special - 1921)
To disassemble a Lefever Nitro Special, first ensure the shotgun is unloaded and the safety is engaged. Open the action and remove the barrel by locating and turning the barrel release lever, usually found at the front of the receiver. Once the barrel is removed, unscrew the stock from the receiver using the appropriate tool or screwdriver. Finally, you can access the internal components for further disassembly if needed, but be cautious and take note of the assembly order for reassembly.
My brother can tell me when it was made. And he is never wrong.
Mfg 1925. Serial numbers are stamed on the barrel flats, on the water table (receiver) and on the forend. They should all match.
Your LeFever 16 in good shape is worth about $300. In excellent shape about $450. It is hard to grade a shotgun without seeing it. Most of the ones I have were good to poor. Your Lefever Nitro Special was actually mfg'd by Ithaca Arms Co about late 1921 or 1922. Ithaca Arms purchased the assets of Lefever Arms in 1916 and started Mfg Nitro Special in 1921. A friend of mine recently purch'd a 12 GA in fair to good condtion for $150.
