As a general rule of thumb, if you know the version number you can download any Kindle for PC release.

The major version (currently 1.14) and unique build (currently 43019) just need to be plugged into the right place(s).
Amazon doesn't usually bother to pull the old versions.
EDIT: You can also find an incomplete history of past versions in the
Winetricks revision history.
Chocolatey unfortunately is having issues with their moderation queue and has only 3 versions listed, also they are not up to date at all.
