Identification of Japanese pen with Music nib

[readytotalk]

Hi, I hope someone can help with identification of pen with Music nib.

The pen is 132mm capped and looks very similar to Japanese pens from 1970s (aluminium cap and black resin pen). The filling system is aerometric.

The cap and barrel have no readable prints, but the nib bears logo.

Thanks in advance!

That’s neat looking, is it a folded nib rather than tipped?

I cant see any fold, it looks like modern stubs, but with 2 slits.

Contact @Bruno Taut, probably he can identify this nib (and the pen).
