    We've got a Piston Provost and an airworthy Percival Sea Prince next door. Provost needs the prop refitting, though. Uses about a quart of oil every week whether you run it or not. 'Horizon' at St Athan.
    I've always liked big round ones.:whistle:

    Oooh who owns/runs them? Call in next time you’re passing and ask if they know of a prop in reasonable but non airworthy nick that would suit a ground runner!!!

    Edit: just re read your post and noted horizon at st athan

    John Sparks runs Horizon. He has a recon prop to go on his flyer but I doubt he has a spare. The ICAT College at Cardiff airport has a partially disassembled Alvis on their grounds that might be another source of info and manuals.

    John is also involved in another Provost oop North that has a 'spares ship' with it so might be a good starting point to give him a bell? 01446 750284

    Found a box in the loft with a reconditioned magneto in, probably came from Coley’s scrapyard. Dated 1966 and in perfect condition with a service tag too. :D

    We were clearing customs at Lydd,on our way to Le Touquet for the w/end and were behind a Carvair (remember them?). When they cranked up those big radials, the cloud of smoke was impressive as they cleared the cylinders of oil.

    Starting procedure for the Leonides is to manually turn the prop through 18 blades to ensure the bottom cylinders aren’t hydrauliced on oil :D

    Just looked up the Carvair and it had 4x P&W Double Wasps. Doubt you would want to hand turn them....

    Same trip, going back, we dropped of at Southend. Selected gear down and there was a nasty smell and smoke from under the c/pit. Humm, told ATC and they said b+ off over the sea until you sort it out. Pulled up the access hatch and manually dropped it (Done this in the hanger, but not in airflow. Nearly took my thumb off...)
    Got three greens and rejoined for a straight in approach. No prob, but every emergency vehicle they had were lined up either side of the runway and quite a few spectaters on the roof gallery. One could almost hear the dissapointment as we taxied in :rolleyes:. Did give them a bit of fun later, as we were having charge probs and I had to hand prop it. Not much fun on a Lycoming, as they go round the other way than Brit engines like Gypsys and you have to lean in a bit as lower than a taildragger.

    Aye the Merlin is bad enough to hand turn! Things like the cheetah have a manual turning handle to take them through a few turns to clear the ports

    Didn't the early hurricanes have a flywheel starter system? The flight mech stood on the wing and cranked the f/w up ro speed then the pilot engaged the drive. The old man flew them in France in '39 and I think he remarked on that.

    Cowlings off, bottom 3 plugs out. You can almost guarantee they are locked up.:(

    Exactly :) it’s what they believe caused the provost that crashed a year or 2 ago to go down

    Looking at that mag again @Wallace , it might be for the 14cylinder Leonides major, as it doesn’t match whats fitted

    On radials, I picked up a really good read a while back. LJK Setright's 'The Power to Fly'. All about his view on the most important advances and engines from the early days up to the start of the jet age. He used to write for Car mag and when I saw the book in a charity shop I was interested.Paid €3. I notice it is a bit more on Amazon:o, but still worth it. Some of his comments on radials might amuse you.
    And, while I am at it, Skunk Works is another good one. The story of Lockheeds U2, SR71 & Stealth aircraft. Written by the guy that ran the place in it's later years.
