It looks like you have an early JUF pendulum. The early screws are slightly shorter than the post WWII JUF/Schatz pendulum screws and have a coarse thread. The screw dimensions also vary slightly between different early JUF pendulums, suggesting that they were likely made (or purchased) in batches when the pendulums were made. I don't think you'll have much luck finding an off the shelf replacement for them.

Are you missing all 8 screws?

I have used this supplier for screws - their steel BA screws look reasonably original.

Steel Cheesehead Screws - EKP Supplies - Precision Turned Parts for Model Engineering

They sell taps too, as it’s unlikely you will be able to get the exact thread size.
