Edit: The freewheel body (with small cogs removed) is threaded into the large end. The threaded inset is then tightened down onto the freewheel body, locking it in place. so the large, left hand cogs can be removed. See item F, below.
Thank you T-Mar. The tool on the right in the photo is just what I have though there are no makers markings on it. We have other Eldi and VAR and Campy tools so I'm familiar with those brandings. Not a hint on our version of this tool. I also checked on the size and threading as PastorBob suggested. Our tool does not fit a Suntour FW body, too big. Your suggestion and the detail notes lead me to wonder if this tool is designed for specific makes of FWs. As I said before, we have a few more of these though they look like the tool on the left (above) and are not marked in any way. Not hand made either. Curious. Rummaging through those boxes has been fun. I pooled all this bits that were FW removal tools and sorta looked like FW removal tools. I'll check tomorrow but I think we have a few of the "extracting insert" things shown in the diagram as detail D and E. Neat.
On another note, one tool I found was a vintage spoke nipper for triming spoke ends of a built wheel. I showed it to my friend and how to use it. He flipped with happiness. We do restorations that often require rim replacements thus all new spokes. He now knows that he can stock fewer spoke lengths and nip to size. Life will be easier. Oh, yeah, got vintage thread rollers too. Livin' in the past.
Thanks everyone.
Edit: eh, I just noticed that T-Mar did note three specific FW makes that this too was used for. I wonder if that's the full list. It may be just try and see what fits. As with many vintage bike tools.
