This AC Mains set has quite a distinctive frontage, but it's main
disadvantage is the glass dial, which is detachable, but is vulnerable to
accidental breakage, or to over-zealous cleaning, which, could wipe the
information off the scale. It was made in 1947, employed lw, mw, & sw bands, and had continental -style "loctal" valves - ECH21 (X2), EBL21, & AZ31 (octal).
