Re: AVO Multimeter survey
Another early Avometer for the survey: 13-range (DC) Avometer, Serial No. 4151, (Douglas Street production) has just sold at auction for £102.
I would estimate its date of manufacture to be around 1932/3. It is in very good cosmetic condition and appears to have the original, fixed, test leads.
From the price it would seem that at least two people were very keen to have it.
PMM.
