Scored another long-sought model kit, though this one does not quite rise to Holy Grail status.
1963 Airfix 1/72 scale Hawker P.1127 (prototype of the Harrier series). There are zillions of Harrier models out there, but only Airfix produced one of the P.1127.
This was $17.50 on Ebay, which is a good price. Another seller wanted $62.50 for one (eeek!) but it was signed by Roy Cross, the artist who produced the dramatic Airfix box art of the 50s and 60s.
