True that, so even though they're not "jazzette" sizes, they were available. Ludwig did allow one to order whatever size they wanted, so in this case, it may have been either a Jazzette set with a 14" deep bass or a Downbeat with an 18" diameter bass (minus L-arm cymbal mounts?). maybe the extra 12" and 18" was ordered later, or at a different time. If you're planning on splitting them I'd look for the 12" and 18" that don't match as far as serial numbers and then sell those first and keep the 18/12/14 together. An 18x14 bass is still very, very rare and will net you a nice chunk of change. Ludwig catalogs were not intended to become historical documents. They were used to sell drums.
I agree that that could happen. However, I do find it a bit uncanny how often these purported "Jazzette" kits turn up with 14" deep bass drums. So often, in fact, that it's almost like there was some kind of trend to forego the iconic 18 X 12 bass drum size. I can't understand why that would be. It was the one thing that really separated the Jazzette kit from any other jazz-sized kit of its day. Why would there be such a plethora of "Jazzettes" with "custom-ordered" 14" deep bass drums? It doesn't make sense to me.
Yes, people did make custom orders for kits back then. It happened. But, it's much more likely a case that kits, which corresponded to the named configurations in the catalogs, were the ones sent to dealers. The marketing scheme back then was not aligned with random lists of ascending/descending drum sizes that customers could choose. It was aligned with selling "model" configurations.
But, most of all, I find it EXTREMELY unlikely that a customer, especially back in the original days, would be so particular about that kind of custom detail (the 12" vs. 14" discrepancy, I mean). That's just a guess....but it's an educated guess because I grew up back then! ;)
Also, why is it that just Jazzettes have this peculiar 12" vs. 14" deep discrepancy so often? You certainly don't see that being the case nearly as much (if ever) with Super Classic or Downbeat kits' bass drums; And those configurations were probably 800 times more common than Jazzettes! There were tons more of those models sold to customers and I can't think of one example of seeing any Super Classic or Downbeat kit showing up with 16" deep shells. Can you? x-mas2
I suspect there is some kind of alternative reason why such an "odd" sized grouping of drums coalesced into this one particular kit. If I was gambling, then I'd bet on it. x-mas3
The only way to get a better idea is to see the pictures (including interior shots of the shell), badges/numbers, etc. It would be essential to check to see the style of the bass drum spurs and exactly how they were installed. Same thing for the railmount(s). Until then, it's really anyone's guess.
I love discussions about Jazzettes! Burger Kin
