Dad's Army 'Don't Panic' Desk Bell

My son who has visited The Tank Museum many times since childhood, became ill with coronavirus and had to self isolate.
The bell was a fun way of attracting our attention when needed, and a reminder of his adult visits.
It has a clear “ding” and arrived very quickly, thank you

It's something that I always wanted and never got given, now it' 55th anniversary and it looks nearly emerald.

Lovely gift and great service
