It's always neat to see what is "common" in the UK that is rather rare in the US. A Lotus like that would be a real steal over here, and you have way more hand cranks too! In fact most of the older ones I've seen in the US are UK made. I don't think Singer made many of them in this country.
Just like the Lotus decal was only put on UK made machines, and the Red Eye was only put on US made machines. And back then, companies didn't' import/export like they do know.
