Old Black & White

I have an old pint bottle of Black & White and was wondering if you could tell me just how old it is.
It was left in the estate of my father-in-law, who passed away about 12 years ago.
It looks identical to one I purchased in London back in 1966.
I am posting images of the bottle and close ups of the front and rear label.
Markings on the bottom of the bottle are
SA870
P
23

We will try to have your bottle of Black & White dated! Thanks for the pictures!

This bottle of Black & White is from the late 1960s. This front label was first used in 1966 and continued to be used until the pack was changed in the mid 1970s.

Since the bottle is unopened, any idea on what it might be worth, not that I will be selling it, Just curious.
