My guide says yes...the "Hercules Grade Double" discontinued in 1946.
That depends entirely on the condition although it won't be worth a great deal in any case.
questionI have a Iver j w/ initials CFGG only 20ga and no other markings, Says on side I /J Arm&Cycle Works
There is usually a screw on the top of the receiver in front of the hammer or a pin through the side of the receiver holding the firing pin in.
$500
The serial number is hidden on the frame under the grip. Removal of the grips will expose the s/n of you gun,then it can be dated. A great source of information on Iver Johnson firearms is The book "Iver-Johnson Arms & Cycle Works Firearms 1871-1993" by W. Goforth
I have a Eastern Arms (sold by Sears and hardware stores) Manufactured by Iver Johnson as well as others. It is a 16 gauge single barrel shotgun model 1929. The firing pin is removed by cocking the hammer back, there is a set screw at the top of the receiver , when removed the firing pin can be removed from the hammer side;watch for the spring. Installation is the reverse.
Excelsior shotguns were mfg. in Europe by Liegeoise D'Armes a Feu. The Excelsior name was also used in the US by Iver Johnson Arms and Cycle works
Theate Freres of Belgium if it is a double with outside hammers. Crescent Fire Arms if it is a hammerless double. Iver Johnson Arms & Cycle if it is a single shot.
There were 3 models of the Iver Johnson supershot revolvers.The first model was made from 1928-1941 and was marked 22 supershot on the left side of the barrel.The second model was made from 1932-1941 and was marked .22 Supershot Sealed Eight on the left side of the barrel,The third model was marked as the model 844 and had a unfluted cylinder.This was made from 1955-1957.
That will depend on which Iver Johnson you have. The one most commonly encountered is the single shot Champion which will range from $25 for a parts gun to $150 in like-new condition. If it has a matted rib, add $25 in all grades. If it has a ventilated rib, those prices nearly double. Then there are the Skeeter Model and the Super Trap, both single shots which run from $375 to $1100. A Hercules Grade side by side double barrel lists from $250 to $550 and the Silver Shadow, an over-under double barrel manufactured in Italy for Iver Johnson, lists from $150 to $350.
Iver Johnson made single barrel and side-by-side double barrel shotguns from 1909 to 1956. Over under doubles were also imported from Italy. The values of the guns can go to $2000 for an excellent example of the Skeeter model double barrel with prices tumbling fast for lower grades in less good condition. It would be best to have a local gunsmith evaluate it for you at a nominal charge.
