eBay and Craigslist finds

does anyone know how to spot these falcon-made models? i personally have no idea, and so as a rule, i just avoid all merckx frames with the logo in a yellow band, but i'm sure i'm also ruling out some really nice frames as a result of this.

It's pretty clear if you look at dropouts, lugs, braze-ons, seat stay caps, componentry, geometry, clearances, etc...
