Hi Graham,
More than the first suspect!
070000 decodes to 6V-AAA has been used twice. Once by DC-3 which crashed around 50 years ago and by a Jodel now broken up
11607C doesnt decode
3C67C9 doesnt decode
406953 G-WIRG Embraer ERJ 135BJ Legacy 650 c/n 14501184 Air Charter Scotland. Registered yesterday, looks like a callsign swop.
Cheers
Alan
