PrimeFaces did not keep track (tag) of versions of the showcase before the 5.0 release. The earliest commits in GitHub are of April 2014 and version 4 was released in October 2013.

Before that, Googlecode was used and they migrated the code AND history from 'svn' to github. That code is in https://github.com/svn2github/primefaces-showcase, where you can easily go back to October 2nd 2013 where the 4.0(-SNAPSHOT) was updated to 4.1(-SNAPSHOT).

Browsing the repository for that version (or downloading it!) is possible. Might be that you need to go 1 commit back but be creative... it is still all there.
