Markings on wheellock pistol, ca. 1630-40

[Matchlock]

Here is another Netherlandish wheellock holster pistol, ca. 1650-55, dated on the grounds of the rounded lock with beveled edges and the barrel changing from octagonal to round without a noticeable staging - very similar to the one you posted, Jean-Marc.
It was found in the mud of the river Hase in Emsland, near the Netherlands border, and is preserved in astoundingly good condition, with all the original wooden parts still there; the mounts are of brass which is also typical of post-1650 firearms from Holland and the far Western parts of Germany (Aachen, e.g.).
