On my desk, alongside my keyboard, I have a round metal tin with the label Hedges L260 Snuff - white background, black lettering. I keep paper clips and drawing pins in it now.
Underneath the logo, it says Hedges L260 Snuff Ltd, Birmingham, England.
My grandfather took snuff and I expect it was a tin he bought, so that would put it 1940-1950 or even earlier.
So, with Singleton & Cole, it would seem that there were two snuff companies in Birmingham.
