Any of you guys own one of these old warhorses? If so, perhaps you'd consider lending me a hand with some data. Very briefly, I'm putting together a non-firing replica built on a dummy receiver, and have thus far accumulated a few parts - mags, bipod & trunnion, grip & mag release assembly etc., and will soon be fashioning side plates for the lower frame. I have some very accurate Ordnance Department drawings of the Chauchat and it's various component parts, but they're not full size and no measurements are listed. That said, if I had just two or three measurements from an existing Chauchat I can easily work up an equation for scaling up measurements taken from the drawings. All I need to know are the O.D.s of the receiver tube, ventilated barrel casing, and mouth of the flash hider, and I can take it from there creating a full-size set of machinist's drawings. On the same topic, if anyone knows of a parts source - particularly for the front sight/flash hider assembly, I'd sure appreciate the information. My sincrest thanks in advance for any assistance.
