A re-re-revisit on the Bundy and Bundy Special saxophones:
* There definitely were Bundy Special baritones. Those have rolled tone holes. I've seen a couple really bad photos (think the Bigfoot film) and I've read a lot of posts from people that actually have them.
* One rule of thumb that recently got shot to pieces was that I could say, "Plexiglas left keyguard? Keilwerth serial number? It's a Keilwerth!" There are a couple problems with that.
-> Paraphrasing Helen, Dorfler & Jorka was sued "in the early 1960s." Then, "around 1965," Keilwerth bought out Dorfler & Jorka and "the partially finished saxophones that Keilwerth assumed from its takeover of D&J that had not yet been engraved were given Keilwerth key guards and a traditional neck fastening screw. The D&J saxes that already had their engraving, for example Jubilee, were then assigned a Keilwerth serial number." Earliest post-buyout D&J I have pics of? sn 35467 (1959). That doesn't line up with the year Keilwerth sued D&J, so, that needs more research.
-> Take a look at this horn, specifically the bell-to-body brace. It's not something you'll find on other "real" Keilwerths. Maybe one could say that UP TO sn 542xx -- that's 1965, so the date looks good -- Keilwerth made the Bundy/Bundy Special, then D&J made them. 54xxx is also about the highest serial number I've seen on Bundy/Bundy Specials. You might also note how that meshes with the date the H-Coufs came into production.
So, while I like the theory of splitting up the manufacture between the two companies, I'm going to fall back on something Helen said, earlier: D&J never had tooling to build baritones or sopranos (and I also need to check to see if there were Bundy/Bundy Special sopranos), so, provided the horn is a baritone or soprano AND has a Keilwerth serial number, it's a Keilwerth. That's the best guide I can give you until I can find more horns, at least.
