Hi William,
it seems "Cooper and Goodman" made firearms..and seem to have been based in Birmingham..found this...
"......Mr. Goodman’s connection with the gun trade was of long standing. In 1838, when in the employ of the Scholefields, he entered into partnership with Mr. J.R. Cooper, and subsequently with that gentleman’s brother, Mr. Charles Cooper, the business being carried on at first under the name of J.R. Cooper and Co., and afterwards under that of Cooper and Goodman, until 1888....."

So on that basis the blade was presumably manufactured , at the latest 1888
Here on this page , Lot 869

"An UNUSUAL .500 Cal. double barrelled Medium Game Rifle by Cooper and Goodman"
and half way down on this page...

"A fine and rare 1856 Pattern rifled service pistol, 25.5cm sighted barrel fitted with rear leaf sights, border engraved lock stamped "1858" over "TOWER" and with a Crown over "VR" at the tail, full stock stamped "WD" and "COOPER & GOODMAN",
After hours of searching ....I'm all googled out
Perhaps it is rare ...hopefully one of the 'firearm boys'
may have further information on Cooper and Goodman......please
William will post a picture of the 'point' soon
Kind regards David
