European Black Powder II

Two more pieces I am trying to identify and place a value. Looks like a French Flint Lock Pistol. Appears very well made I would guess about 1800?. It has straight rifeling and the bore is about .600. What it appears to say on the flint lock is "Guillemin Paris". There is a Antoine Guillemin at 316 Rue du Doyenne, Paris 1784 to 1803.

The second is maybe Belgian precussion, no rifeling and the bore is .550.
