Book value ranges from $280 for a 10% condition gun to $1,000 for one in 100% condition. By the way, are you sure it is a Lewis? All of the 1903 production I have seen are Crass variations. Additinal Answer - According to the table in "Ithaca Gun Company...", the Lewis and NIG were both made in 1903. 1901 was the last year for the Crass.
this is a Lewis model made between 1905 1910.
This should be a Lewis model, made in 1902.
Ithaca SN 68814 was manufactured in 1902 according to Ithaca Gun Company records compiled and released in 1960. It is a Lewis model if hammerless and New Ithaca Gun if it has hammers.

Its the Lewis Model, from c.1905. In 60% condition, I would expect to retail at $350-$400. sales@countrygunsmith.net
You have a Lewis or NIG model, built in 1903.
If the shotgun is a hammerless double, it is a Baker Model produced in 1899 (per Dixie Gun Works, Ithaca Serialization Guide) That serial should be a 1926 production NID. sales@countrygunsmith.net

how much is an Ithaca model 37 shotgun worth in fair condition
The gauge is stamped on the water table by the serial number. It is a Flues model made in 1924.
Perhaps you mean 1907. In any event, it is the 'Crass' model Ithaca shotgun made in 1902. Value is dependent upon grade and condition. sales@countrygunsmith.net
