Blue Carmens Lantern

Hiram Piper Lantern with CPR stamped on a brass plaque
2 blue lens and 2 red lens, which leads me to believe the lantern was used by a carmen. The brass tag reads Hiram Piper Co Limited makers Montreal. Hiram L Piper started in 1902. With the absence of the "L" in the name I Believe the Lantern is pre 1902
