I'm trying to find info on my norco monshee. should be a 1975 because it came with that years black dura ace group. Nice burgundy-ish frame, lugs/details in chrome. I ca't post pics yet but I will soon. The serial number is MAYBE 76D92539 - it's only the first "7" that in question. Stickers say japan. no stickers left on tubes that denote the name, just headbadge (w/ maple leaf). Help? Thanks!
