If you're looking for a comprehensive listing of J. Keilwerth serial numbers, I suggest you look at the one compiled on No knowledge of German is required.

J. Keilwerth was first a Czechoslovakian company—when they had their company in Graslitz—and then later a German company, when they forcibly removed, and relocated to Nauheim after WWII. Exact dates for the move & the resumption of saxophone production is rather debatable, since available German information is a bit contradictory. Therefore it is difficult to say if a particular horn is Czech or German (unless the stamping is clearly visible).

It is safe however, to assume that horns made after 20000 are made in Germany. Anything before, is likely made in Czechoslovakia. (Hits: 18908)

MKX (21)
Keilwerth writes the following about this model:

The Julius Keilwerth MKX Series marks the next evolution of the saxophone for this historic brand.
By combining tonal characteristics of the legendary SX90R along with physical characteristics reminiscent of vintage saxophones, the MKX Series allows the player to have the best of both worlds; a modern sound with a vintage feel.

The name MKX was chosen to pay tribute to those who have contributed to or inspired the development of this new line. The letters “MK” represent Markneukirchen, the historic town in the same region of eastern Germany where the Julius Keilwerth brand began in 1925. Boasting a long history of musical instrument makers and manufacturers,
Markneukirchen is now home to the factory and skilled workers who carry on the traditions of their forefathers, and whose craftsmanship is essential to the quality of this instrument.

In honoring the kinship to the legendary Julius Keilwerth SX90R Series, the letter “X” reminds us of the influence and inspiration from those who paved the way for our success. While the MKX and SX90R series do share some characteristics, they can be likened to cousins who share a common blood line, but have individual qualities and personalities that allow them a unique voice of their own.

The Julius Keilwerth MKX Series is a professional level saxophone that will offer German quality engineering and manufacturing at prices competitive to the global scale, and allow a new generation of musicians to use Keilwerth Saxophones in bringing their voice to the world stage.

Student (32)
These "Student" model horns were built during the 70s and 80s.

According to German saxophone historian Uwe Ladwing, JK's student horns were built by 3 different companies over a period of 4+ decades. Since the 1970s Julius Keilwerth student level saxophones were made first by Amati, then by B&S, then by Amati again, and finally by Jupiter. (The company has recently dropped all student horn sales under ownership of the Buffet Group.)
