Here are a few from my collection. First is one of those from the 1911 catalogue - you can see the glass is white at the back - to be used with torches with bullseye but no reflector. It is overdriven at 3.5 Volts - real rating is more like 3.
Second is a smaller diameter version.
Third is an Ever Ready type.
Fourth is a 1930's Ever Ready - now with coiled filament but still set low into the bulb as per the old range. When buying old torches, these are more common and work well, just losing a bit of character compared to the very old bulbs.
Last is something I knocked up - a Lilliput to MES holder that works well with older torches - because the filament is low down.
