What do you want to know about Ernest Gordon ? (Ernest not Ernst, he was from Sheffield, but I think Ernst is the more common Swedish spelling and you invariably see his bits listed as such on their sites).
I've been collecting his pieces for approx 5 years, and was lucky to meet him a couple of years ago (now sadly passed on) but am still in contact with his wife. My goal in the next year or two is to publish a book of his pieces - almost there ! (just need the time)
He worked at Kosta for few years, and Afors for much longer, then came back to the UK.
I'm aware of 4 "production" ariel pieces he did: yours and the three below. (the same bowl was made under two numbers - I've got both and can't see a difference).
I've also two others (unsigned), one shown on this message: http://www.glassmessages.com/index.php?topic=24729.new;topicseen#new
and another that's the second one below, but flared out into a bowl - I'll see if I can post a pic.
He seems to have used similar signing codes at both Kosta and Afors G for Gordon and then H, G, S etc etc. (ie same as Lindstrand LH, LG, LS)
Approx value ?
I've not seen 193 sold before.
GH 194 (bit bigger vase) went for around $800 - $900 in 2004 (2 sales), time has moved on, but so has the credit crunch.
If you ever do decide to sell, do let me know - always collecting his bits for the book
