[Blenheim]

Don't forget that unit code YH was also worn on Blenheims by 21 Squadron. They were of course a UK based unit, in 2 Group, but they did a detachment to Malta from 26/12/41 to 14/03/42. During this time they lost 12 Blenheims, one of which crashed near Tripoli thus making it a possible for the identity of the aircraft in your photograph. In addition to this, they returned to the UK by being disbanded on 14/03/42 and re-established on 15/03/42, at Bodney. But their Blenheims of course, remained on Malta and were used, possibly still bearing the YH codes.
