Years ago there was a great deal made about the differences between D\u00f6rfler & J\u00f6rka and Julius Keilwerth necks. At the time, Paulo from Just Saxes, was one of the few people who had had any experience with the D & J brand, and had gone on to publicly write about them on his website.<\/p>\n
Fast forward 4 or 5 years, and you’ll find quite a bit more on the ‘Net. Most of that information is available here on this site, on the previous D\u00f6rfler & J\u00f6rka page<\/a>. That page is a culmination of years of research by myself and Uwe Ladwig,<\/a> a sax historian from Germany.<\/p>\n The following table is a further piece of D&J research that has, until now, been lacking. It addresses the fundamental question: What are the size differences in the neck and socket openings between a\u00a0D\u00f6rfler & J\u00f6rka tenor, and a\u00a0Keilwerth Toneking or The New King, of the same era?<\/p>\n The table is a comparison of 8 horns. Two D&J horns are the first ones noted along the top (my De Villiers and a Boucet belonging to a fellow from Austria). The next 2 listed, the Toneking and The New King, are the Julius Keilwerth models that D\u00f6rfler & J\u00f6rka copied. The last 4 are just a random sampling of vintage horns for comparison. The Klingsor and the Mark VI, happen to be the ones I used a few years ago to illustrate the mouthpipe openings<\/a>.<\/p>\n

Unlike my 1957 tenor, which is a stencil of the Toneking, and therefore has a high F#, Paul’s doesn’t have a high F#. His is The New King model tenor, from 1958.<\/p>\n During the course of our email exchange, Paul decided to measure the mouth pipe openings and tenons of his horns. Because I hadn’t measured my horns earlier, the results were not what either of us expected. Although his and my measurements differed to some degree\u2014in part no doubt, depending on exactly where we placed the callipers\u2014one thing is consistent: the necks of the D&J horns have larger tenons, and do not fit into the socket of the JK horns.<\/p>\n Furthermore, Paulo from Just Saxes, mentioned that:<\/p>\n
