I have the same problem. I plan to take the existing spindle to a LBS and dig through their bucket. Some LBS's tend to save old parts, other pitch them.
(I am too cheap to buy something new, as the bike cost me $5)....
If you are going to keep that crankset for a while, I would remove the chain guard and use oxalic on the chainrings. Then polish them up with NevrDull and they will look great. Be careful removing the cotter pin as the french used an odd size (smaller than the rest of the world). Leave the nut in place while you drive it out so you don't mess up the threads.
