I knew I would get the information flushed out by you guys although I have a problem with the bit about Northolt/Abingdon, PK624.
PK624 was the one that I took apart at Uxbridge around 1961/62 and it was transported to Northolt. It was stripped and painted before going to the South side gate alongside the A40.
After that time it may have gone elsewhere and Uxbridge may have got another one but PK624 with bits of PK110 attached to it was the one that Jim Dell and I moved from Uxbridge.
It is good to see that it has survived and may one day make it back into the air.
Thanks Guys.
