Prophet 600 end cheek and keybed screws

Hi,

I opened up my prophet 600 to get the Gligli chip sitting tighter in the socket, which worked, and when it came to putting it back together I couldn’t find the screws!

The ones I’m missing are the screws to attach the keybed to the bottom chassis, and the flat head sunken screws to put the wooden ends on.

Does anyone know what type of screws they are and what they’re called? i’ve tried a bunch of things and can’t find the right ones anywhere.

It’s massively frustrating!

Any info would be greatly appreciated.

Many thanks,

Henry
