Turns out the Kodak promo was a 2x aaa. Alluminum body with a gold colored coating.
I had heard that sometimes production rejects were used for promos. This one has a few minor flaws so I suppose that at least in 1988 that was the case. Flaws exist in the knurling on the barrel and the bezel. What a shame to the customer who likely paid extra.
Note, no mention of 7D in '88, but 7C still listed
1988 was a good year for America
I've noticed factory seconds being used a promos that Maglite did as giveaways. I don't have any evidence of this other than what I've seen though.
The Kodak lights were actually purchased by Kodak and they weren't Maglite giveaways so they shouldn't be factory seconds. I have two and both are worn but otherwise look ok but the QC on AAs and AAAs was never very good because they were a less expensive light. There are many Maglite giveaways but only a handful of laser etched ones. The ones that come to mind are:
Lillehammer, Remember Sarajevo, Olympics AAs
George H.W. Bush AAAs
George W. Bush 2001 and 2005 AAs
9/11 3Ds
The 7Cs were discontinued in 1989 right before Mag started laser etching bezels on their full size lights so that's why they still show up. 7Ds were discontinued in 1982 after only 3 years of production so that's why they're not there.
1988 was a good year for America. Fox body Stangs, Metallica!!!, and Magnum P.I.. Need I say more!!
