Three other clocks with almost identical friezes are known to exist:
1. Private collection, Milwaukee, illustrated in K. Maurice, Die Deutsche Rderuhr, Munich, 1976, p. 70, fig. 527, with associated movemement.
2. Muse du Louvres, Paris, inv. no. O.A. 675.
3. Private collection, Strasburg.
All of these clocks are likely to have been made in the same workshop as they have identical friezes; the Strasburg clock case bears an Augsburg stamp seemingly confirming the present clock's town of origin.
