vintage glass tumblers w/ birds and leaves, clear etched wheel cut pattern drinking glasses

Set of four vintage drinking glasses with etched or grey cut birds and leaves, maybe Libbey / Rock Sharpe? This seems to be an uncommon pattern, I hardly ever find patterns with birds!

These glasses are 4" tall, they hold 8 ounces brim full. No chips or rim roughness, no clouding or finish wear to any of these. A nice older set in very good condition.
