Yashica minister-d : two questions

[Joao]

Hello
1) Which of those screws should I use to adjust the RF horizontal alignment? And which of them sould I avoid to mess with??
2) There is a ring of decaying black foam around the rewind axis. What is it for ? Should I replace it ??

I don't know myself, but you might try asking here:

Electro 35 G-series cameras also have mentioned foam. I replaced it with matching piece cut from pre-optical age mouse pad.

The foam is to stop dust from building up inside the camera, especially in the range finder assembly.

Dust can easily enter via the rewind shaft where it passes through the camera top cover.
