The frame number is probably under the cable-guide, (I think I can see the last digit?) and on the steerer.
Iirc Dave used a 'first two digits=year' numbering system so if you find it it'll tell you what year the frame was built. Those logo-embossed seat stay caps alone imply a 'not before' date some time in the '80s. I believe criterium bikes have an extra bit of bottom bracket centre to ground clearance over the 10 1/2" that was standard for road bikes.
I've taken the cable guide off (Unfortunately don't have the spanners for the headset) and have found the numbers pictured below. The yellow marks look to be discolouration over the years as they don't come off with cleaning.
I can make out a 2 2 4 (possibly 1) 0
With a sideways diamond symbol with the letter O (or D) followed by possibly an L but all I can make out is the bottom of the character, like an underscore _
Any thought on what this might point to? I had thought the first two had worn away over time and was in fact an 8 for '82 but upon closer inspection this does look like a 2.
