sportsmen

They appear to be wearing running spikes, so I’d suggest they’re track athletes . The items they are holding look like ceremonial torches. Was there a 1921 athletics event they were representing their Country or County at?

I’ve found a Mooncoin Howley involved with Coursing Clubs in 1921, but I think that’s a red herring.

The device in the right looks like a leather case for the device in the left.

Orange Order Harriers, by the look of them. They have hunting horns (and bowlers).

DannyM8 I would agree with that neat line of stitching and that looks like a clip at the top. Gent with bow tie has some thing on his lapel. Photo date says circa 16th March could it be taken on the 17th and that is a sprig of shamrock.

Victor Thomas Trumper (2 November 1877[a] – 28 June 1915) was an Australian cricketer known as the most stylish and versatile batsman of the Golden Age of cricket, capable of playing match-winning innings on wet wickets his contemporaries found unplayable. Archie MacLaren said of him, "Compared to Victor I was a cab-horse to a Derby winner". Trumper was also a key figure in the foundation of rugby league in Australia. Some notable highlights of Trumper's career include scoring 292 against Tasmania, including a century before lunch (1908); scoring 100 in 58 minutes against Victoria (1906); 201 against South Australia (1913). His innings of 293 for an Australian XI against Canterbury (1914), scored in a little over three hours, was made in partnership with Arthur Sims (184 not out), and their stand of 433 still remains the record for the eighth wicket in first-class cricket, and Trumper's innings remains the highest score by a number nine batsman. His last 68 first-class innings, from 1910 to 1914, gave him an average of 60. His ability as a batsman, however, cannot be valued by averages or the number of runs scored. His mastership was shown on bad wickets, for when other batsmen were struggling merely to keep their wickets intact, he was still able to time the ball and execute strokes all around the wicket. In February 1913 a match was played for his benefit between New South Wales and the rest of Australia which, with subscriptions, yielded nearly £3000. Trumper was named a Wisden Cricketer of the Year in 1903. Source: en.wikipedia.org/wiki/Victor_Trumper
