G'day mate
I think you might find that the only place the pom-pom was used occured at W Beach. I have put the relevant paragraph from the Despatch of Vice-Admiral John de Robeck, commanding the fleet operations at Gallipoli which was printed in the Second Supplement to the London Gazette of 13 August 1915.
Landing at "W" Beach.—The 1st Battalion Lancashire Fusiliers embarked in " Euryalus " and " Implacable " on the 24th, who proceeded to positions off the landing place, where the troops embarked in the boats at about 4 a.m. Shortly after 5 a.m. "Euryalus" approached "W" beach and " Implacable " " X " beach. At 5 a.m. the covering ships opened a heavy fire on the beach, which was continued up to the last moment before landing. Unfortunately this fire did not have the effect on the extensive wire entanglements and trenches that had been hoped for, and the troops, on landing at 6 a.m., were met with a very heavy fire from rifles, machine guns, and pom-poms, and found the obstructions on the beach undamaged. The formation of this beach lends itself admirably to the defence, the landing-place being commanded by sloping cliffs offering ideal positions for trenches and giving a perfect field of fire. The only weakness in the enemy's position was on the flanks, where it was just possible to land on the rocks and thus enfilade the more important defences. This landing on the rocks was effected with great skill, and some maxims, cleverly concealed in the cliffs and which completely enfiladed the main beach, were rushed with the bayonet. This assisted to a great extent in the success of the landing, the troops, though losing very heavily, were not to be denied and the beach and the approaches to it were soon in our possession The importance of this success cannot be overestimated; " W " and " V " beaches were the only two of any size, in this area, on which troops, other than infantry, could be disembarked, and failure to capture this one might have had serious consequences as the landing at " V " was held up. The beach was being continuously sniped, and a fierce infantry battle was carried on round it throughout the entire day and the following night. It is impossible to exalt too highly the service rendered by the 1st Battalion Lancashire Fusiliers in the storming of the beach; the dash and gallantry displayed were superb. Not one whit behind in devotion to duty was the work of the beach personnel, who worked untiringly throughout the day and night, landing troops and stores under continual sniping. The losses due to rifle and machine-gun fire sustained by the boats' crews, to which they had not the satisfaction of being able to reply, bear testimony to the arduous nature of the service. During the night of the 25th-26th enemy attacked continuously, and it was not till 1 p.m. on the 26th, when " V '"beach was captured,that our position might be said to be secure. The work of landing troops, guns, and stores continued throughout this period and the conduct of all concerned left nothing to be desired.
Again, Hamilton mentions them at Sedd-el-Bahr in the first Despatch of General Sir Ian Hamilton, Commander in Chief of the Mediterranean Expeditionary Force, printed in the Third Supplement to the London Gazette of 6 July 1915.
Above the upper entanglement the ground was scored with the enemy's trenches, in one of which four pom-poms were emplaced; in others were dummy pom-poms to draw fire, while the debris of the shattered buildings on either flank afforded cover and concealment for a number of machine guns, which brought a cross-fire to bear on the ground already swept by rifle fire from the ridge. Needless to say, the difficulties in the way of previous reconnaissance had rendered it impossible to obtain detailed information with regard either to the locality or to the enemy's preparations.
The gun used was the 3.7-cm Maschinen flak, usually called the "flaming onion" gun, so called because tracer was used for sighting. The gun was a license-built Vickers pom-pom, essentially a heavy-weight Maxim machine gun produced as a 1.5-pdr (37-mm) and 2-pdr (40-mm). Guns of this kind served as anti aircraft guns on various Allied naval ships. It had an effective slant range of about 3km for aimed fire with a fire rate about 300 rounds per minute. The guns were never considered reliable since the fabric ammunition belts did not handle the larger cartridges and jammed often and after only a few shots. That is why they were employed by the Turks in a static defensive role which required clean conditions and good maintenance.
Hope this helps.
Cheers

, usually I make a notation, but for what ever reason I didn’t and now I am frustrated as I know I have read it.
