Switchman's Lantern

Adlake Hiram L. Piper Switchman’s lantern. The lantern measures approximately 9½   inches high (not counting the metal handle) by 6   inches in diameter at the base. Wooden handgrip on handle. Excellent condition. Not sure of exact age. I found it when I worked on the extra gang for PGE, north of Fort St. John,BC, in 1971… it was a used lantern then. Asking $125.
