This pattern is thought to have been made only in crystal by Duncan Miller. There is no record of Gillinder Glass Company reproducing either item & this is not one of their colors.
Since both items are in the Smoke colour, we believe it makes them part of Tiffin's production circa 1959-63.
However, the owners are submitting as Duncan Miller due to pattern familiarity. There is currently an on going discussion regarding whether Tiffin reproduced this pattern in the smoke color. This listing will be updated if evidence is found that this is the case.
