pair of ornate antique Victorian vintage cast iron architectural window sash lifts

Antique vintage cast iron architectural hardware.. a pair of window sash pocket lift handles. These sash lifts measure about 4" long, 1 1/2" across and about 1/2" deep in the pocket. Each of the handles is stamped on the back side of the lift pocket with a trefoil clover with "Y & T" inside the clover.

These are in very nice condition with some light rust in areas.
