British Airways Concorde G-BOAC engineer service light bulb

These bulbs have recently been removed from inside one of the engineer access panels located on G-BOAC that is on display at Manchester Airport by the fantastic team who look after her.
The removal was due to the amount of replacements being needed and LEDs making this easier.
Each bulb is Approx 3cm and comes with a certificate of authenticity. Every single one has been onboard G-BOAC since it’s flying days.
A real piece of affordable aviation history!
