I wouldn’t be too scandalized. First, I’m guilty of only posting movements here from the teens to 1922, so mostly before the Precision factory was in play.

My perspective would be, almost anything “Precision” after Precision starts appearing on the lady movements (I think 1922ish) was at least finished in house. There are a few Guild outliers with the odd “Precision” irregularly on movements—I think only from Frey, who was branding “Precision” on his in house movements and a bridge with house markings was used inadvertently.

I think the V1-4 & UV line of pockets was truly in house, Gruen’s specialty to a fault. All brands (even Lecoultre & PP) had to diversify by using ebauches or white labeled movements for at least some sizes, particularly ladies movements & recangles/ovals.

There were always ebauche suppliers in the mix, but the reorganization at the end of 1921 moved us very close to your system:
-Precision finished in house
-A 1-2 year consolidation of the Guild network
-EP calibers gradually replaced by guild & discontinued
