I have a question regarding the operation of this fuze.
I understand that the internal coil spring is a pull spring that holds the primer down. Upon impact this springs tension is overcome by the inertia force and the primer hits the needle in the top of the fuze. But I can't see how is the spring secured in the bottom part (red arrow). The top part seems to be fastened to a nut. (green arrow). And I am puzzled how such assembly was fitted together.
Any insight is welcome.
Thanks Bob
