Based on the serial number, your shotgun was manufactured in 1923. Without knowing the condition and other options, a value cannot be determined,
It's part of the serial number.
The Lefever was mfg. in 1935.
The lefever Nitro special was made by Ithaca Arms from 1921-1948.That being said i believe that yours was made in 1927.I do know that you can contact Ithaca arms and they will date your shotgun for you.
From what I can find they are selling at auction for between $1200 and $1900 for most models.
