I can't find a cross-reference for that number, but Eastern Arms was a trade name used by Sears Roebuck. Most of the shotguns were made by Stevens/Savage.
I was informed that' some Morsel shotguns were made by Navy Arms Co.
Turn of the century
Eastern Arms Co. was the trade name placed on inexpensive shotguns and revolvers made for Sears. The Sears part numbers 101.XXX were made Savage/Stevens although the 101.18 isn't listed on the site I visited. You may be able to match your model using a gun values book for the photos or going to the Numrich web site (gunpartscorp.com) and looking at the Savage/Stevens pictures.
Chances are it was made by HD Folsom or Crescent.
