French cuirass second Model first Type (1807) Mark for ID ?

[Cerjak]

Also I would like to have an opinion about the internal lining .
Inside the breast near the shoulder one mark “KRU 1859” for "Krupp"
Outside in the breast and back plate a crown and GF (Gewher Fabrik)(for the Royal Rifle Factory Amberg), , and also 2 matching numbers with AA for the size
Any comments on it are welcome.

In rhe internal face of the breast one pocket for the "Feldmütze"

The "Crown", and the "GF" show that this must be a Bavarian cuirass, made or at least proofed by the Bavarian "Gewehr Fabrik" at Amberg.

.........and the "Z" could perhaps be the mark of ZIGONI, a man who collected arms etc from the battlefields and sold them to the Bavarian governement.
