I have inventories for Friesland ships in 1652

One interesting thing that I received in the last few days were photographs of inventories for hired Friesland ships in 1652. They don't have the weights of guns, but they are detailed inventories, which could be useful for analysis of ships characteristics. They could also help to estimate values for ships for which we don't have inventories. One little nugget is the the hired ship Schaepharder seems to have been built in 1643 and had a main battery of just 6pdr guns. The ship carried nothing larger.
