The yellow color (Canary) is seldom found. The cup's dart pattern is an unknown New Martinsville pattern and debatable. Replacements.com shows the cup (and other items) as #44 Fancy Squares; #44 is the company's Teardrop pattern. The cup is not Teardrop. Fancy Squares is #35.
According to forum members the cup could be #35 or #36 line or neither. All agree more research is needed.
