BTW: Researcher previously explained that JOSTAM was W.R. JOrgenson, W.D. STannard and A.H. AMmann.
Information on W.D. Stannard is here

From a historical book about Peotone, IL 1856-1956 provided by RocDoc
The Jostam Manufacturing Company was founded in 1914 by Standard, A. H. Ammann, and W. R. Jorgenson, for the purpose of manufacturing gun recoil pads for shotguns and rifles. These pads were shipped all over the world. James Kruger, who started with the firm when founded, made the first pads in his garage at his home.
They later moved to the Ammann Building, now owned by the Sportsmen Club, where they remained for approximately 41 years. They operated all that time with the exception of two years during World War II when material was impossible to be had. The business was sold April 14, 1955 and moved to Dallas, Texas, where it is being operated by Buddy Schoellkopf Products, Inc.
