Despite admiring the item, Eric admitted he had no idea who made the bottle.
“But the thing is, you say this came back in 1918, which is quite early,” he continued.
“Most of these bottles didn’t really sort of materialise until the 1920s. So I’m learning something now.”
When it came to the valuation, Eric explained that if the guest wanted to replace the bottle today, it would cost between £100 and £150.
