I have tried to find serial number charts for Keilwerth saxophones on a number of occasions. Usually my attempts have netted me partial listings at best. More often than not there are years missing out of the chart, so its always a best guess.
Then this morning I happened to come across the most complete serial number chart of Julius Keilwerth saxophones that I have seen to date. This chart covers saxophones built by the J. Keilwerth company from 1925 through 2000. This chart also happens to correspond to the research conducted by German saxophone historian Uwe Ladwig.
Perhaps this last fact is not surprising, since the source for this J. Keilwerth information is the German language website Saxwelt. I liken Saxwelt to the English speaking website Sax On The Web—only Saxwelt is smaller in membership, and isn’t in English.
However, don’t let the fact that it’s a German website scare you off. The J. Keilwerth serial number chart does not require any foreign language skills. True the words serial number and production year are in German, but you’ll figure it out soon enough.
So if you’re looking to date your J. Keilwerth sax, check out Saxwelt’s serial number chart. Chances are you’ll find exactly what you’re looking for.
