Enstone airfield was easy to find, but it was frustrating to arrive in good time and then spend 15 minutes driving round in bloody circles trying to get to the sale as it was accessed through a different entrance which bore a small sign saying "sale" - very low key, but I wasn't aware it was a test!
I've uploaded some pics onto Webshots and I'd like the assistance of the corporate mind if I may.
and look for Enstone Bits album.
I bought a absolutely bran new four cylinder WICO magneto which was, I'm sure, designed to run at engine speed. It has a clever little clip on device that contains a half speed gear and the outer bit holds the distributor cap and the rotor. I want it for my T600 Norman and have since been ruminating on its suitability as the magneto on the twin runs at half engine speed. If I run leads from (say) 1 & 3 and 2 & 4, joining them at the plug, that will fire them in the right places - turn and turn about - on a flat twin won't it? I've turned it over in my mind but I'd welcome your comments.
You will see several shots of the small engine I bought, purely out of curiosity and because it was cheap! Aside from the (I suspect) home made steel frame it sits on, the entire 4 Stroke SV engine is aluminium, sump, block with integral barrel and cylinder head. I think it's war department and, as it has a Tillitson carb, WW2 American. I've not seen anything quite like it. The application of some petrol made it go, BTW.
You know these little 300psi Bendix compressors that were fitted to the rear of the camshaft on the right hand bank of Merlin engines? I assumed they were rare and - being a Merlin nut - bought a couple over the last three years. I'm now beginning to think they are about as rare as beach sand as I found another three at Enstone, two mounted on an obviously homemade framework that must have taken hours to build. The wheel is a model steam engine flywheel and has little fins riveted to the spokes to provide a cooling flow of air. Very interesting.
The Homelite engine is actually a tank heater engine and I bought it out of curiosity to see how it differs from my generator.
Chris Bedo pointed out that the other little BTH compressor I'd ignored, mounted on a steel receiver and driven by an electric motor was, in fact used on ABC auxiliary engines. And he's absolutely right! I've uploaded a factory picture from around 1935 and you can see the stumpy finned beast mounted on the engine. I walk up to the next trailer - and there's another one! It's seized solid ("locked, not seized", the vendor told me seriously) so now I can restore them both and add them to my ABC engine. As far as I know, it will then be the only one in existence with both pumps, both compressors and its original dynastart. Neither RAF Heldon nor the Science Museum have a complete one.
See the interesting little pneumatic ram? I wonder what it was used for? Scratch built, I'd imagine - but why?
Prices at Enstone mirrored the gate price - reasonable. I didn't keep an accurate record, but I doubt if I spent seventy quid including the WICO magneto.
All in all it was a grand day out!
