Hi Dennis
I googled "Leonce Vieljeux" and came up with this:
http://en.wikipedia.org/wiki/L%C3%A9once_Vieljeux
It's an French Automitrailleuse. Here's the story in French:

I guess, you've taken your pics at Saumur. Sometimes it would help if you gave mor information
I haven't seen this car during my visit 2004 in Saumur, but I'll return in June
Hope this helps
Chris
