This is a Canadian National Railroad, (CNR) signal lantern. From the HIRAM L. PIPER CO. LTD. (Canadian division of Adlake Co.)
It has HLP, M stamped on the top and on the door it is stamped "C N R" and Patented 1909 12 20, Piper Montreal
It has been fitted with an electric socket and a dimmer switch and a antique style twisted electrical cord. The lamp has all it's original glass lens and shows very well for a lamp nearly 100 years old.
Please note: No attempt has been made to make this piece new. I like to keep old pieces with age and history, clean and showing their age.
The lamp stands 14" tall and 9" wide.
All my lamps are wired for the US and Canada.
