Thanks Jim,
Yeah I don't mind sharing any of the Documents I've found. And I will touch base offline.
On the Neidner rifles in France, I've found a couple pics of the Neidner modified Rifles with the Mann style tapered blocks. This is the clearest pic of one I have found so far that was supposed to be taken in France. But I really don't trust a lot of the info out there anymore, unless I can find proof. To me this almost looks like a sniper school picture since you can see several of them in there. I do have one good pic of a Neidner modified rifle being tested in the states in June 1917 that I found in a newspaper of all places. But I haven't researched this pic below at all, just because I was researching the one like my rifle. But if you can for sure place this picture in France, it would prove it.
