KVK1 Meybauer, marked "L/13" - Tombak or Zinc ?

Here is another rare KVK1.
What do you think? Tombak or Zinc?

Because of the grey color on the reverse Zink ... but the Ni-aloy hindge anchor is soldered to the back . Now I do not think you can solder Ni onto Zink ????? So that would indicate - Buntmetal ??

From these pics I would say: Zink.
