Check out the illustrated parts breakdown and parts listing for the Stevens Model 94. I recall a trade used by Stevens like that name.
As to the spring..it doesn't show in the IPB and PL for the Model 94.Many single barreled shotguns didn't use a return spring. The design of the back of the barrel and the extractor "wiped" the FP rearward as the action was broken. Someone may have added the spring. However..if it was a coil spring...there is nothing specific that makes in a "GUN SPRING"..any spring that performs the intended function BECOMES a gun spring. Our Host as well as Brownell's and Midway USA sell a kit of generic firing pins and return springs for SS shotguns. Brownells also sells 10" lengths of coil springs.If you still have the pieces of the old spring..determine the wire dia...the spring OD and the spring ID. The OD is slightly smaller than the hole it goes in and the ID is slightly larger the the pin it goes over..how many coils you need can be determined by trial and error
As to a POSITIVE ID of the gun. If you list all the markings..that appear anywhere on the gun and list them in the format they are stamped in..maybe I can narrow down the brand. That said..one place to find out what brand it is can be found with aftermarket stockmakers. They have a cross reference from store name to makers names..ask for a quote on a stock set for your gun..if they make it...they will tellyou which gun it is.
You can also find a cross reference list on these sites
There is a company that specializes in making springs of obsolete firearms. That would be Wolff Gun Springs wwww.gun-springs.com
Wow thanks. I'll dig in to that. The only markings on it are NORTHWESTERNER and A516619. Upset as I've taken a lot of time restoring all the wood, and bluing and this silly spring is mucking it up.
The firing pin (just pin cylinder is 4 1/2 cm witha hole at 4 cm
I don't have all the spring parts as my wife thought they were trash. Teh spring is ID 7/10 cm OD 1cm
My bad. Guy at Wisner's says I'm lookign for a Mainspring not a firing spring.
Sorry we do not make any reproductions of the part you are seeking, nor do we deal in used parts/ FYI, you are looking for the hammer or mainspring, as that coil spring powers the hammer, not the firing pin. A LOT of Trade Brand name shotguns were made and sold in the 1910 - 1930 period. Your gun made have been made by Stevens or Iver Johnson.
Again, If it is a "coil" spring..it doesn't become a "Gun" spring until it is purposed to that end.Any coil spring the will produce the energy needed to operate the gun will suffice. Brownell's sells 2 Gunsmith Kits of coil springs. One kit is called "in the hole" springs and the other Over pin springs
each kit contains about a dozen 10-12" lengths of different wire size coil springs. These are intended for arepair of old guns by cutting off a length(usually longer) and trying it...by trial and error you get a working spring. Brownells also sells the springs in the kit as individual replacements. Those kits(in reality) are made by Wolff Gun Springs Inc..You can buy direct from them.
