Union began as the Colton Manufacturing Company in 1893 in Toledo, Ohio. The name was changed to Union Fire Arms in 1905. They were bought out by Toledo Arms in 1913, and in 1916, Toledo Arms was bought by Savage. They made predominantly shotguns. You can probably assume yours was made between 1905 and 1913. DO NOTfire modern shotgun ammunition in it unless it has been inspected by a competent gunsmith first. It may bring a good price from a collector, if you want to sell it.
