How to purchase old version of winclone?

I am interested in winclone to move a bootcamp windows-xp installation from an old iMac (with bad macOS FS, but still windows is ok) to a newer iMac.
I have connected the old iMAC in target mode viai firewire to the new iMac (running 10.14).

Which version of winclone is needed (may 3?) and how can I purchase an old version. I see only winclode10 on the site.
