What is the clamp size of the AVA stems?
Yah, yah, I know about the death stem 
I changed my stem but I want to use the AVA stem for another French project. Looking for bars for it. Are those things 25.0 or 25.4? Need to find a swept back type handlebar for it. If it is 25.0, wonder if I can wedge a 25.4 bar onto it?

They made both. 25.0 for the domestic sales and also 25.4 for the non-French export market.
I agree with Grand Bois, you should be able to use a 25.4 bar in a smaller diameter stem clamp. Maybe not easiest fitting choice. But especially with a swept back bar the bend angles are less difficult to finesse through a tight clamp opening than many drop bars. And you can certainly just pry the stem open a wee bit more and it will close right back down when the binder bolt is tightened.
FWIW... It was never the clamp area of the infamous French Death Stems which had snapped. On the two examples I've seen, it was the extremely thinned hollow extensions toward the rear of a long stem which had eventually failed (those old stems were not strong cold forged alloy)... and I've also seen photos of another which had completely broken around the quill, below the top of the headset.
