Regarding the recent tubing discussion, I have lurked and learned. Here's what I have to add to the discussion: "The "Dragonfly in Triangle" mark denotes tubes of "tipo Liebellula" Tubi Conici per Cicli, Castello Mario e Figlio - Torino. Chrome Manganese or Chrome-mily (sic) tubes". This information taken from photocopied page of an old German catalog.
Thanks to Kevin Gosney, albeit 13 months late!
So did they just make fork blades and stays, or did they make complete tubesets as well?
