Colnaghi, Dominic Henry ( - 1950)

22 March 1950
Capetown, South Africa
Post Office plate owner

Colonel Dominic Henry Colnaghi, of the Royal Engineers, claimed that he had been given the 'Post Office' plate as one of a number of curios found among a box of clothes belonging to his great-aunt. This was some time in the 1880s. The 'Post Office' plate came to light in 1912.

Colnaghi was related to the long established British firm of Colnaghi's, dealers in fine prints. He was the son of Sir Dominic Ellis Colnaghi and was not related to Sir William or Lady Gomm, as early speculation erroneously had it.
