All, The Label you are referring to is applied by the equipment mfgr, and has only a loose correlation to the vintage of the Trimble unit inside the case. The label has a bar code, a mfg serial number, the date the production bar code was issued, the Andrew/Grayson assembly part number (A002206.G1), and the revision letter of that assembly. Although I've never looked it up, I think Rev E changed the 3 dB splitter to a different model. If your case either has a small splitter attached, or 4 holes in the top cover where the scrapmonger ripped it off, it is probably a Rev E. That says nothing absolute about the vintage of the Thunderbolt inside.
