That was "Mr M" v Blackburne, first published in the Illustrated London News on 10 May
1884 (probably playedat the Divan when Blackburne was convalescing). There is also floating around a very similar game Milner-Blackburne supposedly played in Manchester (ending 10 h3 Bxh3 11 Qxa8 Qg4 12 g3 Qxg3+ 13 Kh1 Qg2#) but I have no primary source for that.
I also found three postal games played by E. B. Lowe ca. 1879-1881 and you possibly
already know Charlick-Mann played by post in Australia in 1881 (1-0, 72).

Dr. Harding's response adds to information about the Blackburne game, from the Illustrated London News, giving "Mr. M" as the amateur player of the White pieces. Other (not primary) sources have named this person "Milner".
More importantly, the Illustrated London News account of May 10,1884 helps focus the possible date of the game, usually given as 1880 - which I had challenged, based upon an article in August 15, 1885 issue of the Brooklyn Chess Chronicle. So, 1884 is the corrected date. Finally, Dr. Harding is being modest in merely mentioning the three postal games played by E. B. Lowe correspondence games, as a good while back he provided them for me.
