As a fitter and machinist these photos interest me intensely and gives insight into how the operations were carried out. Obviously the Ryder machines the cylinders but I'm trying to work out how the cylinders are held. It looks like they are being held by the top fin but surely this would not be sufficiently rigid to carry out machining of the sleeve bore and the stud holes and facing off of the cylinder base.

I just did all that and amazingly works as specified! More to the point I think you are right! How on earth did they keep it all square? Judging by the cylinder muffs I have seen most bores I have to be out of square..If you go to the image on the website that David has given, open up the work folder, right click on the image and select `copy image`.
