Only seen one clear mercury running in person. I'm hoping to change that, but they're such rare lamps!

Work of art the way these old GEC lamps were made. Think I have the 400W too, definitely have the 250W version.

I agree, those lamps (not only from GEC) were very well made back then. There was more consideration for the value for customers than for shareholders.
