Hey, Helen: the 1959 catalog's interesting because it's got the "angel wing" models AND both New King and Toneking models are listed. The other fun thing is that the bari -- New King only -- has sheet metal keyguards. Makes that bari you sent me pics of more interesting!
I have a couple of possible theories for this: 1. The baris ordered by Ravoy were custom ordered with the Lucite guards, or; 2. Since the bari I sent you pics of was a couple of years older, JK abandoned the idea of putting so much plastic on a horn in the 2 years that had elapsed.
A couple of other random thoughts that crossed my mind while I was reading through the JK catalogue...
Firstly, it was possible for customers to order their The New King models with a metal key guard, instead of a Lucite one. The ad states that on this page. Actually, I realize it says the same thing on this page as well. This is the first evidence that I've seen that JK offered these metal angel wings for sale to its European customers.
Secondly, the price of the horns is interesting. The New King tenor in 1959 cost 621 DM in the silver plated version. This Dörfler & Jörka-stencilled Original Hopf Classic--also in silver plate--cost 600 DM in 1956 when it was new. Check out D&J's version of the angel wing. So far I have documented 3 (I think it's 3) of the D&J horns with these angel wing key guards. All of them have been very early horns (in the 7XXX serial number range). The price however, is what's most interesting.
D&J was not a cheap manufacturer, and their horns (clones of the JK The New Kings & Tonekings) were actually very good. Clearly, their prices were obviously just as high as--if not higher than--JK horns. Since I have both a D&J tenor, and a JK The New King tenor of similar vintages, I am in a position to be able to comment intelligently on these horns and how they contrast/compare. I'm planning on doing that later, but for now, I just thought their prices were very interesting.
If anyone here is interested, I recently updated the D&J page on my site again. I dare you to find more written about the brand anywhere... In any language... Including German... ... Yes, that's including what Uwe Ladwig's written about them in his book, or his articles in Sonic sax & brass, or anywhere else. (I've collaborated with him on my page, that's why I can write this with such conviction.)
