Hardly news. Said Puma (ZE449) entered RAF service in 2001, having been used for a variety of ground based purposes before that. Don't think it was ever in a museum.
Correct. Sat in storage for a long time, but not in a museum.
I also believe that some South African Pumas have been purchased/refurbished to serve a similar purpose. However, these have been acquired through more standard defense procurement channels.
6 x S330J were purchased. 2 are in service, 2 are still being converted, and 2 are in storage.
I'm not sure but it might have included the Makela engines being taken out.
Nope. The engines were 4C4, not Makela. More powerful certainly, but still no anticipators.
