Thank you Michael Watterson for what you saw what saw. Now I have a question similar to yours: BKS237 and BSK237 is one and the same model or not? On my model there shild labeled BKS237.

King regards

Dear administrators-editors,

In this post I posted photo BKS237 model with a range of wavelengths MW and LW. Why are you posted pictures BKS237K receiver with a range of LW, MW and KW? Besides. there are differences in the design of radio boxes:

BKS237 - back panel is not removable

BKS237K - removable rearpanel

Various sizes of box:

 

BKS237 - 350x260x150 mm

BKS237K - 400x300x190 mm

Different connection to battery:

 

BKS237 - spring terminals

BKS237K - another way to connect

This data is sufficient to present a model Braun BKS237 as a new model for RMorg.

Kind regards,

Korniienko Oleksii.

Can someone send me a picture of the orginal knobs of the BSK 237. I am missing some knobs and want to make them by my self. Espccially the tuning knob with the little switch knob I am looking for. Has someone these knobs for selling? The KK2 socket is of a IO (8 pin) type instead of the P8 type. Is this orginal or maybe replaced?
