HG116 was a Warwick, but I do not know of any in service at Sharjah,
... not Sharjah based
per se, but Halley (Sqns of the RAF - 1980) has the following on 294 Sqn:
In November 1944 [based at Idku in Egypt] Warwicks supplemented the Wellington and in addition to ASR missions, the Sqn also flew anti-submarine patrols. In June 1945, No 294 moved to Basra and supplied detachments for the Persian Gulf and Arabian Sea areas until disbanded on 8 April 1946.
... so possibly an ASR detachment at Sharjah? Will check Stanley-Price over the weekend.
