At one stage I contemplated obtaining an old overhead projector, with the object of using it as an optical comparitor. Another machine that might have posibilities is a micrfish reader, both these machines are becoming obsolete, but my source of supply has fallen over(literally). I can’t remember whether it was in ME or MEW but a good few years back there were plans for an optical comparitor. Ian S C
