EK1 Screwback L/12 Juncker - Opinion???

[wschmidt]

Hello Guys,
I bought this EK1 of a big EK1 collection.
I never have a Juncker in my hands and I have doubt about it.
It is a realy good Juncker?
Best regards,
Schmidt

IMO this is a interesting piece ,
because this the type a full W&L SB cross 2 type frame type & 2 type inner magnetic core ,
but with a good original marked mark L/12

therefore wrote the that interesting piece
