So the question is: are there any generally accepted dates as to when EGA's started being made thinner, "flatter"?
I photographed four EGA's this morning, two thick and two thin. The thin ones are very moden while the thick ones include the one I got at the show (the bronze 2nd from left in the photo) and one on the far right which is shiny gray, almost brown looking. All are screwback.


And if anyone has a guess as to the vintage of numbers 1 and 4 I'd be interested in hearing that.
