The Silver Squirrel has dated this piece to the 1930s.
I would date them to c1920-1940. They have a very stylish Art Deco design with gilded bowls and handles engraved LB or BL. They are in superb condition being free from dings and repairs. They measure approx. 5.5 inches (14cm) long by over 1.25 inches (3.3cm) wide and combined weigh 154 grams. Beautifully made examples.
