WW2 British printed REME badge

This is a single badge that normally was added to an uniform as a pair.
One for the left and one for the right upper sleeve.
Printed badges are getting harder to get these days and this is a perfect mint example.

This is a badge that was carried by members of the Royal Electrical and Mechanical Engineers.
Or better said, those who fixed the vehicles, build bridges and blow up stuff!

I only have a single badge, so sorry, no set!
