Ron van Maanen, for some reason. lists Pieter de Bitter's ship as being from the Middelburg Chamber of the VOC

I was surprised that Ron van Maanen lists Pieter de Bitter's ship Mercurius as belonging to the Middelburg Chamber of the VOC. Our other sources, such as Witte de With's journal for 1653, indicate that the Mercurius belonged to the Amsterdam Chamber of the VOC. In May 1653, the Mercurius carried 36 guns and had a crew of 110 men. The dimensions were 122-1/2ft x 30ft x 12ft. The height between decks was either 6-1/4 or 6-1/2ft. The Mercurius was sunk at the Battle of Scheveningen, on 10 August 1653. Captain Warnsinck, in the book De Retourvloot Van Pieter de Bitter (1664-1665), mistakenly described the Mercurius as carrying 40 guns and having a crew of 200 men. Sources:
