Lamb’s Demerara Navy Rum. I don’t know exactly when this was bottled. Research has shown that this style of bottle was available in the 1970’s (and before). The UK largely stopped using their own “proof” calculation in 1980 and began showing the ABV rather than the proof. Whilst this is noted as 70 proof on the bottle, it’s the old “British” style proofing so it translates to 40% ABV. The same ABV Lamb’s Navy Rum is today.
