Dirck Scheij's ship the Achilles

I have a page that actually spells the name of Dirck Scheij's ship as Achilles, not Achillis. The page says that the ship carried 28 guns and had a crew of 102 men, sometime in later 1652. The armament is listed as 4-12pdr, 12-8pdr, 10-4pdr, and 2-2pdr guns. The Achilles was hired by the Admiralty of Amsterdam. This may have been a case of a ship that was sold in 1648, at the peace treaty with Spain and then rehired by the admiralty. Some of these ships were eventually repurchased, it seems.
