Originally founded in 1835 under the name of the Z. Bisbee Co. and known today as Osborne Coinage Co., it is America's oldest private mint. In 1943 the mint was acquired by Clifford Stegman Sr. and two partners as Osborne Coinage Company. Today, it is operated by Thomas Stegman and his sons Jeffrey and Todd.
Osborne holds numerous distinctions. It minted the 1860 presidential campaign medals for Abraham Lincoln's successful campaign, and for eight other presidential candidates. During World War II, Osborne was called upon by the U.S. Government to mint 5 billion food ration tokens, causing production to reach 80 million tokens a day. ...
I spoke with a employee at Osborne. He's more or less become their "historian". He told me that as old files are found, he saves the literature and enjoys keeping track of all of their past products, etc. but not much was writtin years ago so not much to look back on and the main owner passed away taken a lot of the history with him.
He was surprised that Osborne Coinage made carabiners. First time he had heard of it! I am sending the pictures to him for his files.
The most he could provide was what he had already contributed to an internet article:
Founded 1920 by Wiley W. Osborne as Osborne Register
Company. That same year the firm had purchased the Murdock
Stamp and Speciality Company -- headed by James Murdock Jr.
(q.v.) -- which, in turn, traced its roots to John Stanton (q.v.)
the area's first diesinker. While the exact date may be nebulous,
Osborne uses 1835 as the firm's founding date. In 1944 W.W.
Osborne sold the firm to Dayton Acme Company, which later
named it Osborne Coinage Company."
He did say that he has literature from Osborne Register that remarks that during WWII they made pilot survival equipment and parachute "clips" for the war effort. But he thought once the war ended and the company was sold to Acme that they stopped making military equipment.
That looks like a carabiner we used to call "Army Ovals". We bought them at a hardware store here in Boulder. They were grey in color instead of the usual aluminum color and were prized because they were cheap and slightly larger than Bedayn ovals which made them good for racking pitons. There were never very many of them available here.
