Adler 5-27 bobbin parts

Do anyone know where I can get bobbin parts for my god old Adler class 5-27 sewing machine? I need the bobbin tension adjustment screw. The screw head is worn out and makes it difficult to adjust. I can also use a new tension spring for it, but the old still works. (see pics) I think it is the same bobbin house as in the Singer 45 K and in Adler class 105 and 104 (which is the successor to the class 5 and 4) Adler saddler class has two different diameters on the bob. adjustment screw 2 and 3 millimeter, mine are 2 mm.

If anybody has these parts or know where to get it, please let me know.
