Default Re: AVO Multimeter survey

Hi Johnathan, your meter No.4 will almost certainly be within 1951-1956 date range; it is the first iteration of the Model 8. Difficult to be more precise than this!

It may be possible to lessen the smoke staining on the scale with a cotton bud soaked in wd40, but probably not remove it altogether.
