J.C. Higgins was the "store brand" of Sears. Companies such as Savage, Mossberg, High Standard, Winchester, Marlin, etc etc made guns for Sears, but marked them J.C. Higgins (later years, Ted Williams)
There will be a number on the barrel that you think is a serial number, but it is not. It is the model number- something like 583.105 or something like that. Post the model number, and we can probably tell you who made it.
The guns were just as good as the parent model, but might have a plainer finish, etc.
The store brand of Revelation was used in a similar manner by Western Auto, and Westernfield by Montgomery Wards stores.
Sears sold MILLIONS of guns under the J.C. Higgins label, and left the gun business in 1989.
What we have here is... failure- to communicate.
