Haven't been following the GB sorry, but that looks damn good to me Geo!
LOVED seeing the PBY-5A (G-PBYA) recently at the Airwaves airshow in Portrush, Northern Ireland. Undercarriage and wingtip floats were extended and retracted during part of the display: wingtip floats took about 5 seconds to fully extend, same to retract, and (don't know if this was usual for the type, or just for the display) nose gear was fully retracted first, then starboard side main gear, and a few seconds later the port side gear.(Just some useless trivia for yas, I thought it was interesting)
