Hi Eddie,
Cracking pix as allways and a fine collection. I agree with your timeline and recall buying some of these tins at a fair a while ago. The late John Rothery once told me he used the Eley name on his Wasps for as long as he could get away with it.
Slightly off topic but do you have any detail on the BSA Diabolo tin - it's not one I am familiar with?
Kind regards,
John
