I saw a pair of the (large) grey ones with original shades sell for $600 (USD) just recently! :shock:
Don't get me started on the shades, though - the lamps have a fitting size all of their own! I had to buy a shade with a European-size ring, buy two European-to-UK shade adaptors, glue them together, and then cut a larger hole in them with a drill before I could have a non-wobbly fitting shade on it! :lol:
But if they were new in 1975, that puts them into some kind of time perspective. Thanks.

I have to admit, the style does scream of Michael Bang - and the period is about right (there are distinct similarities with Bang's Atlantis range from 1981) - but I don't like to guess at these things.
