I have the "final" version (3rd time was the final). The first two weren't bad and the final was just a minor tweak from the second model. D2F used to make a cover, it was discontinued about a year before Tom's passing and the company closed. I inquired to several custom cover companies but Studio Slips was the only one that would take on the project.
Pictures, below, are of V2 but only a slight adjustment of the zipper and the end handle opening on the final version.
