I am relative noob when it comes to D7 and drupal.org, so apologies for any deficiencies in issue etiquette, I will of course provide any missing information if/as required..
When I try to Add content > Gallery I have no save or preview buttons as I have with other content types.
Here is my drush output for the module and dependencies:
