Unfortunately I could not find a complete scan or detailed picture with cpo and instructions. If you'll ever get these I'll be more than happy to create a complete vector version.
As for the bezel I recreated in vectors (upper part around the actual screen of the game) I would dare to say that it's the most accurate available and as close as possible to the original. Not sure about the actual measurements but graphics are correct as you can see here and here.
Different topic: would it be possible to access the Mame artwork FTP ? I'd like to contribute to the project.
