PMs from some informed sources and some wording used in a recent posting by him have jogged my memory. I have the distinct feeling that I have met Adastra sometime in the late 80s at either Brampton or Wyton. I would be grateful for any assistance; what I recall for now is a shortish, rotund Chief Tech or WO ground trade type - he may have smoked a pipe and possibly had a small moustache. Does this ring any bells with anyone? If so, I'd be grateful for a PM or comment below - it's time we ID'd this stroker for definite.
