Possibly not relevant to this particukar gun, but certainly relevant to the overall discussion: From what I've read, bill C17 limiting magazine capacity in automatic and semi auto firearms phased into law in Canada between '92 & '94.
Since the IC guns were imported well before this, this is why we never see one with the 5 round Canada pin in place.
Hey sagebrush, what's the finish of the stock look like? Tons of varnish slathered on over existing the original finish (shellac) especially on the inside surfaces? That would be indicative of an IC.
