keys on ESB guantlet laser & jet pack the same part?

Could these be the same parts Some kind of rubber molding cut up into pieces?
ALSO check this out all you ESB NUTZ.....In the behind the sceans photos on the REF CD there is an added key on the top of the laser box above the other keys and I think I saw one on the bottom too in a pic somewhere. In most pics there's only the three on the side.
