Thanks, Colyn, for that further bit of information. Yours sounds like mine. Can you elaborate just a bit? For example, since yours had the raised L seal that would, according to the first post in this thread, indicate it was manufactured in Germany. So how do you know yours was actually made in Canada?
EDIT: Okay, I missed noticing Tom's post when I posted the above remarks/question. Tom's explanation about the larger M3 engraving alongside the serial number correlates with my understanding that mine (and your's Colyn) was made in Canada. And Tom's explanation about the raised "L" being used, to denote made by Leica/Leitz regardless of whether the camera was made in Canada or Germany, certainly sounds reasonable to me.
