Installation of older version

I am using ROSFlight with a plugin that needs an older version of ROSFlight in order to work. The plugin requires the msg file GPS.msg which is not present on the newest version in the master branch. I tried reverting to an older version/commit but so far the ones I have tried give compilation error with I make ROSFlight. Is there a specific version/commit I can use that has the GPS.msg file and complies with ought errors.
