...I find that JP Clabrough & Bros was used from 1870 to 1883 when it then became Clabrough & Golcher.
...In 1893 it became Clabrough & Johnstone...
Clabrough was a British maker. William Golcher (1834 to 3 August 1886) was a retired American maker in St Paul.
http://www.damascus-barrels.com/Golcher/text4.htm#INDI7.4 Golcher went to England to visit his mother who was in poor health. At this point she was estranged from his father James, a Philadelphia gun maker. How Golcher and Clabrough met is unknown. Clabrough offered Golcher a partenership in his guns made for the American market. William thought this a good way to provide for his family and bought in. They set up shop in San Franscico. Later, Golcher bought out Clabrough's interest in the American operation. A Golcher continued to run the business until the late 1940's.
Larry Shelton is the leading researcher about Clabrough. He also has had contact with the Golcher family.
