Sourcing spare parts for chairs ?

[Philip]

I’ve lost the screw & plastic cap that connects arm rest and back rest. Any place where I can source this or any tip on alternative fixing ? For now it’s held with a strap but obviously not the most durable solution. For sake of good order this relates to the camping chairs.
Thanks in advance.

A company called ea metallbau sent me some spare parts
a few years ago.
I believe that they have been taken over by this company http://www.westfieldoutdoors.eu/de/
