The clock is interesting in the 3rd and 4th pictures. I've got one lurking, it's supposedly as fitted to some MIG fighters but boy is it a heavy thing. And not a very easy shape to cut a hole for either since although it is sort of circular, there are two smaller arcs of circles with a non obvious centre.
I've seen them sold for over £100, but I got mine a lot cheaper from eBay, even if it was a slightly worrying wait for the post as it came from the Ukraine!
I've been looking at those. The one's I've seen mounted on MK's dashes seem to have a polished rim. I wonder if the standard paint finish can be taken off and the alloy polished sufficiently well?
