[OT} What weapon is that?

[Dragongirl]

Funcken is a last name in and around Belgium. I believe he may be referring to a gun reference book authored by a Funcken.

Edit : Such as :

L'UNIFORME ET LES ARMES DES SOLDATS DE LA GUERRE EN DENTELE/ Funcken

or

Arms and Uniforms: The Age of Chivalry, vol. 1, 2, and 3. by Lilane and Fred Funcken
