Canadian Military Engineers

[fougasse1940]

Not much info on this badge, Except that it is rare http://www.britishbadgeforum.com/for...tary+engineers
But what is this exactly, short lived version? Makers fluke? Were they ever worn?

Is there any documentation on Canadian Engineers cap badges available? I would like to compile a complete collection of cap badges but am clueless what is out there. All I managed to find on the web is this http://www.cmemuseum.ca/index_e/visit_e/faq1_e.htm which for starters doesn't list different versions e.g. OR's, OSD, embroidered, collars worn on caps etc..
Where to start?

Rgds, Thomas.
