3-1/2pdr guns in 1629

An interesting feature of the guns carried by the Rotterdam ship Postpaert in 1629 is that the ship carried two "Spanish" guns firing 3-1/2 pound shot. These would be roughly equivalent to English falcons. The Dutch also used guns firing 2-1/2 pound shot in the early 17th Century. These were similar to the English falconets in shot size.
