I can't believe that Brits are drawn to a brand
called "Smeg", however.

It's an initialization of "Smalterie Metallurgiche Emiliane Guastalla".

There used to be ads showing a boy delighted at the delivery of a Wurlitzer
musical instrument: "Gee, dad, it's a Wurlizter!".

I can imagine a comparable ad with a girl enthusing about the new kitchen
appliance: "Wow! It's a Smeg, ma!".
