• Two surviving
harpsichords (1750 and 1768), both have a single manual and have only two 8' choirs and a buff stop, with all battens protruding through the instruments side, similar to original
Ruckers instruments. • Kottick mentions four bentside
spinets (1763, 1765, 1766, 1770), all with a single 8' choir. A colorful fifth bentside spinet signed "A.D. 1738" and bearing a rose with the initials AD, has been attributed to him as well. • Three
clavicytheria (1751, 1752, 1760), strung like his harpsichords with two 8' registers, and guidebattens protruding through the cheek. The clavicytheria have an elegant pivot mechanism of Delins' own design, needing no spring action and only gravity for the return. Chung describes Delins clavicytherium thus: "[he] succeeded in overcoming the difficulties of building an upright harpsichord better than any other builder. His three instruments, which are considered by many to be the finest of all surviving clavicytheria, have an amazingly fine touch that is achieved by a special action that upon the release of the keys allows the jacks to return without the need of springs or additional weights." • The last surviving instrument is even more old fashioned than the rest, a small, hexagonal,
octave spinet (1750). ==Decor of the instruments==
