Made in 1901
You have an Ithaca NID model made in 1926, Not knowing condition or grade 300 -3500.
If that is an old double barrel "New Ithaca Double" it was made in 1926.
Ithaca made 10 gauge shotguns.
It was made in 1914 and "probably" is a Flues model
Made in 1915 - probably a Flues model.
There's a list of serial numbers by year at http://ithacagunrepair.com/page5/page23/
The Ithaca side by side 12 gauge serial 188650 was made in 1927.
I would say that you have a Ithaca model flues double barrel shotgun that was made in the year 1923,with the serial number that you provided.
