Hello all

I bought those two Heuer chronographs few days ago and now I am on a quest for information.
First of all I am interested if they are Kosher.
If not what is wrong. If yes what movements are inside.
My guess is Valjoux 71 and 23 but I am not 100% sure.
Also I am guessing that 3 register is from period before WWII and 2 register is after WWII.
Any information regarding ref. is appreciated. Is it possible to date 2 register chronograph with case or movement number?
I tried to look through onthedash catalogs but I could not find something exactly same. So any help and information regarding those two Heuer chronographs is very welcome.
Same thread is also started on watchuseek forum but they referred to you as being more experts in Heuer.

Here are some pictures of the 3 register Heuer

And here are some pictures of the 2 register
