Those Fullerton badges are puzzling. I'm wondering if they're just a poor quality ink that faded. Rogers could have been using a new printer in California for these new Fullerton badges, and maybe light exposure faded the cheap ink? We have some members here experienced in printing and graphics. Maybe they can explain how black ink sometimes fades to blue, red, or green.
Everything else on these drums (lug hardware, collet noses, tone control felts) looks proper and original for mid Dayton era and early Fullerton shells. The serial numbers and round-headed lug screws on the Daytons date the shells to approx. late 1967 to early 1968. The hex lug screws with no slots and the white tone control pads put the Fullertons at late 1969 to 1970. Of course, the date of manufacture has nothing to do with the date of sale, as these Dayton shells could have been sitting in the warehouse for some time until they were finally paired up with the Fullertons to make a full set.
And despite all the ribbing you took about buying the Rogers Book, the book wouldn't contain this kind of detailed minutia. All these little hardware changes are known only from examining the hundreds of pictures of Rogers drums posted here and on the auction sites. As far as I'm concerned, keep your Rogers questions coming.
Very nice acquisition. If you're not keeping them, you should have no trouble selling them.
