Blimey, I must have had superb bladder control back then or memory has erased any lavatorial sightings of 40612... or the road sign at Mildenhall - first visit was 1979.
My first hearing of a Merlin this year, G-BMSB/MJ627 up from Biggin. Also Monsun G-AYPE, surely the longest serving resident at Biggin - must be 50 years now.
