Turns out I had some time before I had to leave so had a bit of fun, can redo in higher res (thumbnails below so click for larger, forum sometimes crushes it a bit as well) and get a tripod/focus better for the back shots if needs be but should be enough.
For the official one then the micrometer reads in half mm (full rotation of the barrel is .50) so between the flats (ignoring the PCB breakaway rough bits) 28.5+.34 = 28.84mm (or actually halfway so you could imply further but there is possibly parallax and variation along by then as well as maybe compression), vernier was the long side so 35.58mm (.59 on the mic but again parallax and variation).PCB is 0.7mm on the Verniers. I am not putting it back together yet so high res or measuring the wings can be done if it needs to be. Inch lovers *spits* be careful on the vertical ruler on the right as part of it is whitworth pitch calculator/measurer and not plain inches.
