Re: Muntz's Patent Birmingham stamp on Ship's fastener
Hi,
Maybe try to track down the biography of George Frederick Muntz written by C. Carlos Flick (1975): Muntz Metal and Ships' Bottoms,The industrial career of G.F. Muntz (1794-1857)
I would think his biography would have information about the company and where the sheathing, bolts, and fasteners they produced were shipped to and for how many years they were used.
I was looking through a book called Ship's Fastenings written by Michael Mccarthy. It doesn't say much other than Muntz's discovery of a copper and zinc alloy (Muntz metal, 60% copper and 40% zinc) was designed for creating a better sheathing, but that he took out a patent for bolts and fasteners made of the same material in 1832.
Good luck
