Thanks for that info Grant - I wasn't sure about the origins of the Cat.
I normally get down to Cosford at least once a year, so I'm due to go again fairly soon.
It's certainly better for photography at Cosford, compared to how Hendon is now.
Karl and I went to Hendon in October, meeting up with Marcel, and the lighting was terrible, compared to my last visit in the very late 1980's.
The BoB hall was closed, and those aircraft still present were in the process of being disassembled and moved, ready for the refurb.
I just hope they don't go overboard on the arty farty stuff and lighting - I go to see the aircraft, not a bl**dy light show !!
