Mallard freewheel removal?Trevo

I got this little tool that I removed some sort of lockring with it?

Can some one save me?

Thanks

If it's a Helicomatic....cory

Man, I thought I had the last one of those....
If it's a Maillard Helicomatic, and you have the little flat tool with the fancy hole in one end (which is sort of a collector's item but not absolutely necessary, by the way), take the wheel out of the frame and look at the freewheel side. There will be a locknut (both mine are black; I've seen silver ones) in the center of the freewheel that looks like it was just MADE for that tool. Slip the tool over the locknut and unscrew in the normal, lefty-loosy direction. If it hasn't been removed in awhile, it may take some force.
Once the nut's off, you just pull the freewheel off. It will rotate a quarter-turn or so as it comes, but it's basically a straight pull.
To replace, grease the part where the freewheel goes, slide it back on and replace the nut. Doesn't have to be very tight, just snug it up.
Warning: Maillard cogs are getting very hard to find, replacement freewheel bodies are all but impossible, and nothing else will work. But if you lose the tool (I have about four of them floating around my garage, but I haven't seen them in years), you can use Channelocks or something similar to get the nut off.

If you're married to that thing, for a restoration or something, I have at least one 27-inch rear wheel, possibly a 700C rear w/MA-40 rim, at least one freewheel and maybe some odd cogs in the parts bin (I had two Helico bikes, but crashed one and converted the other to singlespeed).
Not sure what's left after cannibalizing them for a few years, but I have no use for any of it. Be glad to send anything you need if you'll pay shipping. Email me at hevydrop@aol.com if you're interested.
