The design of the plinth of this terracotta model provides the clue leading to the identification of the statuette, as it is identical to that of the plinth of a series of statues of Frederick the Great's Generals which were ordered during the Seven Years' War for Berlin and erected in the Wilhelmplatz. In 1759 the statues of Schwerin and Winterfeldt were commissioned from François-Gaspard Adam. However, he left Berlin before executing the statues. They were carved instead respectively by Sigisbert-François Michel (nephew of Adam) and the Brothers Räntz. Further statues were commissioned from other sculptors.

Francois-Gaspard Adam (1710-61), who made this terracotta model, was one of three sculptor brothers. Their nephew, the son of their sister, was the much better-known sculptor Clodion. F-G Adam's best works are probably his garden statues for Frederick the Great of Prussia at Sanssouci, Potsdam.

In features, A.91-1970 resembles the statue of the Prussian field marshall Schwerin more closely than others, and it is thought that it represents F-G Adam's original proposal. However, the statue as executed by Sigisbert Michel is markedly different and full of agitated movement. It is inscribed: 'Commencé par ADAM et fini par SIGISBERG 1769'. The statues were removed from the Wilhelmplatz in the mid 19th century and are now in the Bode Museum in (East) Berlin.
