The unsigned virginal (false-inner-outer) is set in black and painted with fine chinoiseries in the form of birds and vines.

The virginal was restored by William Jurgensson in Lauffen am Neckar in 1988 and it was revised by Matthias Griewisch in 2023 .

According to Matthias Griewisch, the range and the build would point towards an instrument built in the late 16th century by Francesco Poggio.

The keyboard (C-f3 [C, D, E, F, G, A-f3 as short octave]) has a 3-octave span of 48.1 cm.
The c2-scale is 335mm, the f2-scale is 237mm.

Dimensions of the instrument:
Length: 1512mm
Width: 420/520mm
Total height: 895mm
Body height: 220mm

According to Prof. Dr. R. Ewerhart, the instrument was built in Rome in 1699 by Mario Serafini  as a false-inner-outer. According to him, the instrument is signed inside under the soundboard. The current tuning pins seem to be old and are not drilled. A number sequence 169[1?] is visible on the keyboard frame in the centre of the keyboard rest pad. The key c3 is signed with the number 1699 in ink.

The keyboard (GG-c3 [GG, AA, HH, C-c3]) has a 3-octave span of 48.0 cm. The instrument has two rows of new jacks equipped with Delrin.

The c2-scale is 357 mm, the f2-scale is 270 mm.

Dimensions of the instrument:
Length: 2175 mm
Width: 817 mm
Total height: 1034 mm
Body height: 241mm
The instrument was restored around 1981 and 2023 and is in playable condition.

The organ is currently being refurbished in the workshop of Christian Wegscheider.

The maker of this spinet built around 1768 is unknown. Neil Stewart was an Edinburgh publisher and trader of spinets and fortepianos. Earliest mentions are from around 1759-60. James Logan and possibly Andrew Rochead built spinets for him. Burkart Shudi’s account books also show sales of keyboard instruments to Neil Stewart.

Melchior Guante (1759 – 1845), established his instrument maker’s business in Münster, Westphalia, and in 1815, passed it on to Heinrich Niemann. It is supposed that Melchior Guante was one of the pupils of Johann David Schiedmayer. His instruments are lavishly designed and have a particularly robust construction. The Guante fortepianos which still exist all have Viennese action with wooden Kapseln.
