There's a really nice book titled Dutch Muskets and Pistols by Kist, Puype, Van Der mark, and Van der Sloot that covers 17th C. Dutch arms. Skipping through all the different Dutch lock styles there in that time period we see that the round faced 'banana' shaped locks often seen on Hudson Valley Fowlers start showing up in tail end of the 4th quarter of the 17th c. in the Netherlands. The full evolution to that style, based on the last two plates in this book, date one gun to 1688 and the next to 1690. Of course, the Brits took New Amsterdam (New York Harbor) in 1666 and opened the region trade wise which I believe accounts for the wide array if locks, including their own, used by the Colonial Dutch builders through the 18c (see Grinslade's book). The Dutch builders did however hang tough on their own style of carving using the acanthus leaf motif. 'Sorry for the 'ramble', but you struck a nerve (chuckle). Cheers, Fred
