Don't hold your breath. The 1978 catalogue doesn't have any geometry charts. However, it does have a cover photo of an Eddy Merckx look-a-like that is superimposed on another photo, to make it look like he's racing thoroughbred horses. The Soma motto was, "Ride like a thoroughbred". They put Eddy V2.0 in a leather hairnet helmet, Soma cycling shorts and cycling gloves but no cycling jersey - it's a Soma t-shirt!
Pending purchase of a mechanical or electronic angle finder, get out your old protractor. Carefully draw, mark and cut boxboard templates for 70 through 75 degrees and 105 though 110 degrees. You'll have to notch the apex end to fix over the lugs. Using these, you should be able to measure within 0.5 degrees of the actual angles.
