Thanks a lot, Ja, I like your first one best. Gul Rudolf (“Yellow R”) is now based at Halmstad, but I expect you know that already.

For those not in on the joke or who missed that earlier thread, here’s MikeJ trudging along beside the motorway to get pix of the awkwardly located Lansen and Tunnan at Linköping not long ago. Some passing motorists were rather upset at seeing 3 Englishmen on the soft shoulder!

Sorry, I can’t answer any of your questions, YellowSun, I was only there for the air show!
The J29 Tunnan Gul Rudolf was there, and I believe the 2 RSwAF Historic Flight Lansens could be stabled there too. There was no sign of “excess jets” that could be in operational condition, I am no expert on the RSwAF I am afraid, historic aircraft are more my line, being rather “historic” myself! From what I saw there were less than 10 Gripens around, but there were several hangars there that we could not see inside. If you are lucky, someone more expert than myself will read and answer your questions.

“The Sigrist part of the name was Fred Sigrist then Joint Managing Director of Hawker Aircraft Ltd. He helped set up the company so that their products could be used in Hawker aeroplanes.”

Post #4 above mentions the first flight as being from the aerodrome at Desford, Leics., which I guess was the R&S flying base. That post from Charlielima5 also mentions the book that probably contains the definitive answer.
