I've had the deck for some time now (5 years?) and occasionally hunt for resources; I've found very little. It's possible that French language sources are out there, but I'm not fluent so I haven't explored those options. I believe there are several threads over at the Tarot History Forum that address some of the symbols employed, in the larger context of historical tarot, but that's all I can think of at the moment. If I come up with anything else, I'll update here. Thanks for starting the thread, and good hunting to you!
