Friesland Directors' ships in December 1652

One question has been: what ship was hired by the Groningen Directors in 1652? The answer seems to be the Graaf Hendrick, commanded by Jan Reijndersz Wagenaer. I have a photograph of a document dating from early December 1652 that says that this is the case. There were other ships hired by Groningen, but this seems to be the Directors' ship.
