I purchased a new Guerciotti Jet frame in 1982, it was silver, from a bike shop in Philly. I don't remember the JET decal being as obvious as the one in your first photo. I can't remember exactly where the decal was located though. I have had people question me that they didn't think that "Jet" was an official Guerciotti model, but it certainly was. The frame cost just under $600.00.
