Fragment of lock plate of a flintlock of a musket

Fragment of the lock plate of a flintlock. In the cock, a piece of profiled flint is clamped with the help of a screw with an eye. The strangely shaped cock is attached to the lock plate with an axis. At the axis, one of the tracks of the cock, which connects the cock to the hammer spring, is broken off. On the inside of the lock plate, the remains of the rod and the sear with which the lock was fired are still present. The cock belongs to another fragment of the same lock to which a steel is attached (RM NM-7763). It concerns a flintlock of Northern model, originating from Norway or Russia.
