This is a Canadian wartime 1941 model 329BC "Empress" brass fount Lamp finished in copper tone Ivory laquer according to page 1 of the 1941 Coleman Canadian #42 Catalogue. http://internationalcolemancollectors.com/ocp-catalogs/1941colemancanadiancatalogno42.pdf Interesting detail about this lamp is that a previous light green paint probably from the 169K has been factory overpainted and through use is starting to show through as wear on the handle and the fount. No date stamps at bottom of fount.
