Bike Parts USA has the tools, but they don't tell you which one fits his Maillard. I think you need a Park fr-4. I have a fr-4, but the Maillards I have are the dreaded 2 prong type.
When I need a freewheel removed that I plan to toss, I pay the LBS $5 to pull it for me. If I plan to use it, I go ahead and buy the tool.
