You may well be right. My memory is getting a bit dim, but I think we called him the Eng O. I cannot remember what training the graduate NS Eng/Tech officers did - probably not much.
Apart from 208 at Abu Sueir we had the Eng and Admin staffs of HQ MEAF. and all the bean counters, who were mainly civil servants who had been stuffed into uniform because the Canal Zone was on active service. I don't think that HQ 205 Gp at Fayid had much of an Eng Staff. So AO Eng and his staff took an unduly close interest in what was going on in our hangar. Our backlog of mods built up to such an extent that AO Eng eventually ordered that all backlogs would be cleared on the next inspection. Aircraft disappeared on "Minors" for months.
