Re: AVO Multimeter survey
I'm also very surprised they were making the DC version in '58, i would have thought the Universal AC version would have pushed it out sooner, primarily by better accuracy with the larger scale (the glass is also of a sensible thickness..)
The use of smooth-side mouldings for the cases suggests to me there could have been a stockpile of the early mouldings which were dusted off and used when the meter was nearing the end of it's production..? I assume that the later moulding was introduced due to breakages of the early one.
