Good evening ,
I have this tin over 20 years in my collection , it came from a WW2 EOD technician who said it was a part of the Stevens stopper set for stopping the clockmechanism of 17A and 17B fuzes , the meaning should be " Bomb Disposal Sugar " but the story goes that the sugar was used in the "afternoon" tea . Wright or wrong , looking out for reactions .
best regards , Seppe .
