Two styles of small bayonet lamp, apparently unused.
There are some differences between the two linear filament examples, one has significantly more filaments supported at the ends only, the other has multiple supports and fewer filaments.
Age unknown but these are early examples, as the glass envelopes have a pip on the end, left from the manufacturing process.
The clustered filament version has a more conventional style cap.
Royal Ediswan, Made in England. These are 20 watt lamps, and unusually 100 volts, so entirely unsuitable for use on modern supplies.
The end of the bayonet cap is shown here, with the two contacts on the end. Although metal, the outer cap is not electrically connected to anything.
