They were built in France, will have to look up the name of the company that built them. Ended up in Texas, then one went to California (where I got to fly it a few times) and from there on to Peter Jackson’s collection in New Zealand. The other ended up at the Southern Museum of Flight in Birmingham, Alabama. Photos of both here:

The third one is in Belgium at the Stampe Museum:
