Brass or zinc core by weight...an injuiry.

[Robert P.]

Hello all,

I have a dilema. I just received an 'L/12'-stamped EKI , non-magnetic, with 100% paint. I cannot tell whether the core is brass or zinc, and I'm curious. If anyone could please post the weight(s) in grams of their known brass or zinc-cored Juncker cross I could compare it to mine to determine which I have. My cross has the 'Common L/12' frame with the pin assembly commonly found on the Juncker wide frame Schinkel and the 'crunch-bead' frame. It does not have the 'coke bottle' pin, instead it's the long slinder slow-tapering pin.

If you could please help I would greatly appreciate it.

Robert

Thank you, Michal, my friend,

Very much appreciated.

Mine is 17,7g...so I'm assuming it's brass-cored. I don't know if one can be 100% certain of this though. The backplate could be thinner, etc., a number of variables to consider. But, for now..brass it is.

Thank you again,
Robert

Actually I've seen very few (maybe two?) zinc-cored Juncker EK1s, and Michal has one of them. So the right guy answered...
