[Major02]

Hello Guys,
Could you tell me something more about this KC? I would like to know when and by whom it was made.

Thanks!

It's made by S&L. is the core magnetic? This will determine it's age better. Tom

I've only this photo from auction and can't examine it by now.

Looks like either "C" or even "D" frame - not much value if "D" frame.
