These teardrop drawer pulls are beautifully chased with the same patterns used in the 1600's. It is unusual for back plates to match each other exactly, but this particular pattern, an exact copy of an early one, did. Use large drop drawer pulls and small keyhole escutcheons or use small pulls and large keyhole escutcheons. Or use the same size in both places! You will be pleased with the result.
Mixing hardware designs was very common right up until the 20th century. It is only in the last hundred years that consumers began to focus on matching things.
