windswept11,
Your Black & White bottle appears to be a US/Canadian version, which is marked "Blended Scotch Whisky";
versus the UK version which would have been marked "Choice Old Scotch Whisky".
From the markings on the labels, this was produced between 1955 and 1966.
***I suspect that this may have been made for the Canadian market, as the labels do not mention the US
distributor (Fleishmann Distilling Co.) which had been shown on all Black & White bottles since 1936.
Cheers,
