1971 (06) Ulster - Philart - Newry CDS + Newry Plane Flight Label - Signed by the Operator

Very unusual Philart cover...

Full set cancelled by the rare Newry CDS, but then also with a 'Newry 1st Pilotless Plane Flight' Label.............

Then this has been signed by the 'Pilotless Plane' Operator - in today's terms, I'm pretty sure they are talking about a 'Drone', but in 1971 that term didn't exist..... quite possibly, oneof the earliest tests on these !

BUT - on top of that, Newry is located 15km from the Mourne Mountains (3p Stamp) so is actually Cat £125.......... !
