There was never a company with that name. It was a trade name on guns made by Crescent, Harrington & Richardson, and Stevens for distribution by Belknap Hardware Co. in St Louis. Absolutely correct. Do not confuse 'Essex Gun Works' with the current manufacturer 'Essex Arms' which is a maker of .45 pistol components and is also bringing back the Iver Johnson tradename.
$150-$300.
The Essex trade name was used by Belknap Hardware of Louisville, KY. A double barrel was probably made by Crescent Fire Arms Co c. 1893-1930.
No sn data published.
Crescent Fire Arms made millions of similar shotguns with over a hundred different trade names. I doubt if anyone has a good estimate, but there were a lot. 20 gauge will be harder to find than 12s.
$25-$75, depending on condition. Might top $100 if it is still in original showroom condition.
