i created a new destroyable version of the default German field gun from H&D Deluxe using 3ds max.
When you assign a "version" actor and resistance value to it (i.e 6), the gun could actually be destroyed by the player

This is my first destroyable model of H&D Deluxe equipment that i ever made.
I will upload it, so if anyone is interested could use it with proper credits note.
Below i attached an image how the destroyed gun looks like.
Any feedback would be appreciated!
