When I cleared a lot of stuff from the emporium that was Clares motor works in S London there was boxes of those red oxide tins, all empty, all new, I grabbed a few, the remainder got squashed. Who'd a thought they would be of interest one day?
Someone was selling them and some gold coloured ones on ebay for about a tenner a while ago, they are late 40s dated on the outside, I think their value was in the NOS contents including a pair of Romac scissors.
