This reproduction is created almost entirely by hand (using a fretsaw and files) and is not an exact copy of the original instrument, although it corresponds to the original in terms of its form, inscriptions, positions of the stars, etc. The inscriptions are etched instead of being engraved.

This brass instrument is neither varnished nor artificially "aged". Over the years and decades it should be able to develop its own "face". Each instrument bears the maker's mark and number, and is supplied with a description (in German and English)..
