Help IDing some British and European firearms

[RDGAC]

Righto, some pictures for your collective pleasure, so to speak. The upper pistol is the one I suppose to be the elder. Overall length 14.5in (approx); 10in barrel of .625in bore at muzzle, severe wear on lower right quadrant of the barrel wall (looking from the muzzle) which suggests that this may have been closer to .60 when made; has a foresight, with backsight channel cut into the tang.

Fully stocked in dark wood (age patination?), possibly walnut/hazelnut (don't know my woods), carved extensively including beneath barrel and on grip; some cracks present on several areas. Large, scroll-tipped trigger offset to the right, apparently intentionally as its slot has also been carved right of centre; large trigger guard with extensions to end of lock bolster forward and ~0.4in short of the large, rounded butt with metal cap, the langets of which extend to ~0.5in short of the lockplate tail. Ornamental scrollwork on the upper part of the grip and the reverse of the lock area.

Flintlock with etched border on plate and cock, all parts present externally except upper jaw of cock. Remains of upper jaw screw now within threaded part of the cock itself; frizzen spring is also very loose with 5-10 degrees of rotation clear of the lockplate possible about its screw. Mechanical condition unknown, as the lockplate screws are very stiff and I don't want to damage them, which prevents any inspection.
