This instrument is part of the institute collection and was documented to a great extent. It is in original state in all its relevant parts and will be preserved unaltered as a remarkable piece of piano history. The instrument bears no signature, but closely resembles the typical construction of Johann Andreas Stein's grands, but there also are some significant details not present in Stein's instruments and therefore leading to the assumption of a maker familiar with Steins's work yet unidentified.
The reconstruction in comparison with the original work traces found in the original instrument revealed a very experienced and refined craftsmanship of this yet unidentified maker. Thus the instrument represents an early stage of dissemination of Stein's grand model so revolutionary for its age which was produced maybe by a former co-worker with close knowledge of Stein' instruments but individual manners and some technical ideas of his own.
