I did have a near identical one, but in silver as I recall. It came to me from the estate of an elderly lady who may well have had Percival Aircraft connections but never able to confirm it. The back was marked “Fatorini of Birmingham”.

I think that company still exists. They made the DH badges for airscrews, for example. They may still have customer records?

Sorry guys…this is the quote I wanted to use earlier…Doh

Fattorini.co.uk are still in business and if as T1940 suspects they made the badge originally …they might still have old records.
