The main question from the materials presented in my posts:

Where are the artillery pieces from 1801-1815? Other than the one 1807 piece found, there are no others from this period, existent in today's world so far located.

Perhaps these items were recast for political purposes? The French hegemony over the Dutch lands for this span would cause negative thoughts. The feelings of the incoming Royal family could also be a reason.

The Gun foundry in Den Hagen was functioning throughout this period, so production must have been done.

Later guns are stated to be modified models of previous models. What were the modifying.

We have little perspective of the carriages and auxiliary vehicles, even the carriages of present possessions of the museums.

I will try to suss out answers to such questions. Any help/opinions would be greatly thanked.

With respect,
