JohnM,
Here is what I have.
William Glaze, Columbia, SC 1838-1870
Start out as a jeweler with a Mr Bostwright.
Establish the Palmetto Iron-work in 1850.
Associated with a Benjamin Flagg 1854.
The firm became Glaze & Radcliffe 1861
Some guns are marked W.G. & Co., they can have both USA and CSA markings, he apparently was dealing in any arms available to fulfill his contract.
1861 purchased the Palmetto Armory under a contract with the CSA, part of which required the repair and production of arms.
There is a book available.
