Gruen Movement Families and Sizes

I have always struggled with which movement was a Veri-Thin and which isn't, and there was no one good place I could find. Is a caliber 420 a Veri-Thin? How about a 405? Unable to find this information listed directly in Gruen documents, I took on the task of converting the entire Newall Fingerprint Catalog that was Gruen related.

Newall is the only company I know of that labeled the movement calibers with their families (e.g. Veri-Thin). It is the Veri-Thin calibers in particular that were of the most interest to me as the are the most common and yet there was no list of the movements. So, here are the movements along with their sizes in lignes
