The replica was made by the late Werner Iten in 1975. The only difference to the original instrument in its present state is that the nasal stop can be set undamped, which is a beautiful colour for free preludes and toccatas. Although it will always remain uncertain whether at one time the original had an undamped stop, some other instruments from the same period show this feature.
Johann Mayer's harpsichord from 1619 today kept in Salzburg is one of the seven surviving 17th century German harpsichords. It has two 8' choirs but three fan-like registers. The longer choir can be plucked both close and far from the nut and even together, thus creating fundamentally different timbres. In addition, the instrument possesses a buff stop to the longer choir making its sound strikingly similar to that of a real lute. This unique instrument can produce 14 different timbres.

You can see here the three fan-like stops and the buff stop. The photo was made while voicing the instrument with real quills.
