I have more from Nico Brinck

Thanks to what Nico Brinck has given me, including in May, I have enough to make more progress on a Dutch gun model. There seems to be value in switching to metric lengths and estimating the actual bore length and diameter. Unlike the English, gun lengths are not on even 6in intervals. I am also using metric weight measures, the motivation for metric is to be able to deal with things like Rijnland feet and Amsterdam feet interchangeably as well as Swedish feet and pounds.
