Nice work, the only problem is that it is incorrect, all male mk IV had to have the main armament changed to there 75mm guns dew to the fact that they did not have the ammunition to use the British guns.
Not so much the ammunition, but the missing sighting devices for the Vickers 6-Pounders were the problem. Nevertheless, it's true, all Mk.IV Beute males were converted to carry 5.7-cm Maxim-Nordenfelt guns in standard socle mounts (also seen on most A7Vs), which had protective shields of lesser diameter and thus necessitated extra plates to be fixed for covering the crevices. The pictures should serve to illustrate the difference.
