Default An old valve

I couldn't resist this box of valves at our local auction when I saw this amongst the mainly 50's pulls. It has A23 on the pinch which might be 1st batch of 1923. Needless to say the filament is o/c but a nice display piece. It's surprisingly heavy.

I now have 100+ more valves to store in the garage but fortunately there were only a few TV types.
