Trying to find V3.6.5 download

I have some OpenOffice files that are apparently ancient (1.5 yrs??)
I read in the OO forum that LibreOffice 3.6.5 might open those files.

Not seeing the link to prior versions.
Thanks

Try this Link (Index of /libreoffice/old) there you find all old version for all OSs.
