There were two Western Arms Companies.
The best known was the Western Arms Corporation located in Ithaca New York and was a brand name used by Ithaca Gun Company.
The only gun listed for them is a double barrel model named the "Western Long Range", made in 12, 16, 20, and .410, with 26 to 32 inch barrels.
It was available with single or double triggers.
It was made from 1929 to 1946
There was also a Western Arms Company located in Norwich, Connecticut that was a brand name used by the Bacon Arms Company.
Bacon was in business from 1862 until 1891.
Bacon was a maker of cheap, low-grade firearms, especially extremely cheap solid frame, rim-fire revolvers, commonly known as "Suicide Specials".
Bacon-Western Arms guns have little, if any value.
Due to the fact that a Western Arms shotgun was a low quality firearm to start with, and the age, I STRONGLY recommend you NOT attempt to fire it.
These old guns weren't very good to start with and were made for black powder shells.
They are NOT suitable for use with modern smokeless rounds.
FAIR WARNING: These can and WILL blow up in your face.
