This #2 Clydesdale was reissued by Imperial from a Heisey mold around 1983. The pattern was produced in crystal and several other colors, including the Verde Green shown here. It should be marked ALIG, signifying Imperial by Arthur Lorch. Only 326 pieces were made.
Heisey #2 Clydesdale (in crystal only) may be marked on a back leg, or unmarked.
