Hello

At this point I present a few photos
from my new KERN (K. u S. M IV Plate 1406G).

The special feature of this clock is the triangular (hexagonal) case.

I suspect that the brass castings are electrogalvanised gold-plated.

Who can tell me the easiest way to test?

Very pretty! What do you mean to "test"? Looks like the top will lift off once the clips are moved. Then, wind the clock, and make sure the beat is set.

I don't believe they are actual brass parts, DieteR.

The clock runs fine!

I want to test, if it is electrogalvanised gold-plated

Why You don't believe they are actual brass parts? What do You think, the parts are made from?

While I'm sure there could have been variations, over the years, I had a similarly constructed full size Kern where the dial included a place where there was a spot of the plating missing (I'm guessing due to corrosion, but it could have been damage from a drop). If I had to guess, I'd say it was spelter, underneath. Dark gray like cast iron. and not soft like tin, lead or pewter.

You are right. It is definitly no BRASS!

It is no iron, because it is not magnetic.
After testing the top cover on it's underside, the material is silvery and softI
It's probably tin, or, at best zinc die casting.

If you really want to know what metal it is, maybe Herr Kern could be of help. As far as I know, he still replies to questions about their clocks. If he does reply, let us know just as a matter of record.

brasses include a grey color metal.
less copper than the yellow brass.
think more zinc and less copper.
it is supposed to be easy to cast...
