Juncker EK1 WFS: always zinc core?

[wrongplanet67]

Do Juncker Wide Frame Schinkel EK1s always have zinc cores or do they sometimes have a brass core? I suppose these WFS’s never have a magnetic core,

How about non magnetic Juncker WFS EK2s: zinc, but sometimes or never brass core?

I once had a magnetic ek2 juncker wfs

[wrongplanet67]

Yes, but the question concerns non-magnetic WFS EK2s.

Among the non-magnetic WFS crosses, EK1 and EK2, do these only have zinc cores or also brass cores?

[ben bijker]

I had a number of WFS ek1, all had a brass core.

Thanks Ben!

I once found a interesting pieces with WFS magnetic inner core ,but the frame not a WFS type ,but in a so called " long flaw frame "

[wrongplanet67]

I received the following information concerning Juncker WFS crosses:

WFS EK1 - brass core
WFS EK2 - zinc core

And the exceptions confirm the rule.

WFS EK2 - zinc core same used Juncker 3 flawed frame too in individual pieces

Do WFS EK1s exist with a magnetic core?

Sure looks like zinc pest to me.
I think he ought to take measures to stop it's progress!

[ben bijker]

Yep, zinc.
