It looks like this bottle dates from the late 1950s, possibly the early 1960s. By the way, just an FYI - the cap used is what’s referred to as a ‘Kork‘n’seal’ – this was the manufacturer’s brand name. Under the foil there’s a metal cap, and the small lever on the side was used to push the cap up and open the bottle, like on a tin of shoe polish.
