I understood that it was possible to find some valjoux 72 with 806 stamped on the caseback, corresponding to transition between Valjoux 72 and Venus 178 version.
Concerning the BOG or WOG stamp on the movement, can we consider that all Valjoux 72 are stamped with BOG as it was used until 1957 while Valjoux stopped in 1955?

Kurt 's website is probably the best resource out there
And yes, all V72's are marked BOW , and some of the early V178's as well, WOG on V178's started on 56/57 models , i am not 100% sure when the exact switch was , Kurt has a timeline posted on his website , its probably on there ?
Amd welcome
