Your challenge is to find me a replacement bit of glass that goes in my lamp. The lamp is an uplighter, and i need the replacement glass on the pointy down reading lamp bit. The lamp has a sticker that says .'replace any broken glass' and 'replace any cracked safetyshield' and 'ersetze jede gebrockene Schutzscheibe'. It's about 8-9cm diameter circular glass but I have lost the original piece. The lamp was from john lewis about 6 years ago.
If someone finds it they won't be proving that Mumsnet is better than Google.

Take a picture of the lamp, go to John Lewis (pref on a weekday) and find the most senior-looking person in the lamp department. Ask them if they recognise the lamp, and ask them who is the person in the lamp department who has been there the longest.
