The Harp was drawn at home to Smithstone Hibs and enjoyed an easy 5–0 win.

The Harp entered the Dumbartonshire Cup for the first time in 1889–90, but did not win a tie in it until 1893–94, when it beat the junior side Radnor Park 9–0,[8] the club's record competitive victory.

This had decimated the smaller clubs in the county and by the time the Harp was dissolved, there was only one senior side left in Dumbartonshire outside the League.

The club beat Helensburgh Union 6–0 in a first preliminary round replay - the original tie ending 4–4, but Harp, in an indication of the club's problems, having to play out the entire tie with 9 men[10] - but lost 8–2 at Royal Albert in the second.

[12] The club's colours were consistently green jerseys and hose, but the knickers changed in 1891 from navy blue[13] to black,[14] and in 1894 to white.
