20 vintage US postal lockboxes. Doors are approximately 3 1/2 X 5" with frame and door. Post office doors have all parts and are in great working order. The doors are brass and bronze and were made in the 50's and 60's. The doors can be opened with a three number combination. The doors are in the same condition they were removed from service by the postal service. They are a great example of American workmanship made to last forever.
