Although very nice , niether one of those guns are quite right. The FDC should be iron mounted and stocked in walnut. The buttplate screw placement isn't quite right either, there should be no screw in the heal. I have seen one FDC with three screws, one in the toe, one in the heal and one in the return. Only A very few FDC made in St Etienne (200?) were mounted in brass. The sideplate belongs on a fusil detrait.
The Fusil de trait is nice. The lock is completely wrong, it's a Germanic jaeger lock. The buttplate return is too far past the heal and the top screw should go back a little further. Barrel wall thickness at the muzzle should be very thin on both and no swamped exterior.
