@OldSkoolReTool'd Marinoni appears to have the chain stay chromed, but that's not the case for mine. Maybe it was an option at the time; my Marinoni came with a Deore LX groupset so it might have been a more ''budget friendly'' build.Lovely finds. Is the chain stay chromed? I know he did that on the earlier Columbus tubed ones, along with the dropouts, for additional hardness. I've been curious about these for a while, would love to see a comparison between Eastern and Western Canadian geometry of the era.
I'll post some pictures when I'm done restoring it.
