Re: AVO Multimeter survey
Peter,
You're probably right that the movement has been replaced - there is definitely no serial number where it 'should' be, in fact there's a suspicious-looking blank space where a serial number should have been inked-in. The scale plate however is definitely a hand-ruled one, see photo, and the pointer has a red disc which may enable approximate dating.
Note that "Model 40" is cast into the front panel, but the instruction plate on the back says "Admiralty Pattern model 47A".
