Most buttons with backmark Firmins, London in my own collection date from the last quarter of the 19th century.
Both a German (F.L) and a French manufacturer (T.W.&W. / Coinderoux) supplied buttons to Buenos-Aires based firms A.B. and J.G.
Most likely your button is the older one, possibly dating from the initial order in 1875.

Wow 1875!
It's funny I've found it while searching for mushrooms, in a field
