This sounds like an excellent day out, and half the distance to Newark!

Does seem a bit naughty (not the good looks). There are a few people who could promote their wares very well through the forum but don’t.
On topic, what’s this yoke off of? Not Skyvan as listed, or did my brief google let me down?

Glad to see things are moving on. Here’s the bottom right of a late Mk1 panel, with a slot for the starter mag switch and details of the screw shapes. Work is progressing on your labels, including a version of the one pictured. All the best, Ian.

The Merlin is from Hurricane V6958 which came down near Kidwelly in 1941. It was dug up by a farmer doing ditching work and the remains abandoned against a hedge. Abergavenny ATC recovered the substantial remains from the hedge a year or two later, and found the maker’s plate still riveted to the structure, identifying the plane. The engine went to 2478 Sqn ATC museum and when that was disbanded about 15 years ago was rescued and put on display at Kidwelly. I used to clean that engine as a cadet! No idea on the second engine, but likely a sea recovery as the guy who rescued the Merlin is a keen diver. He also organised the recent memorial to the Blenheim crew lost at Cwmavon.

Hello Dom, very impressed with your project. Having very limited metal bashing skills and facilities a Spit cockpit seemed a little unrealistic. I’d toyed with the idea of a couple of wooden frames but you might have stirred me into action. On the panel front, All Mk 1 panels were aluminium, the earliest, as Edgar says have a large flap position indicator top left and two fuel gauges bottom right, they also had a charge control top right and an ammeter below the voltmeter. Even the early ones had a dimming screen slot. Later Mk 1s had a single fuel gauge, no flap lever no battery charge control and sometimes an extra ‘station keeping lights’ above right of the flap lever. There is a good ‘late’ Mk1 repro on ebay at the moment.
I’ve got plans for Mk1 panel, although not scaled. I also make replica panel and cockpit labels which might help you along. Does your school have a large bed laser cutter? Three foot by two should fit a panel and I might be able to sort you out with CAD drawings. Tangmere’s excellent book on P9374 is a very good reference. If you look very closely on page 70 you can see one of my labels! All the best, Ian.
