WANTED a screw that holds the battery in on a St901 FUJIA Auto electro camera

Hello:
I have lost the screw that holds the battery in my camera.
It is a ST901 Fujica Auto Electro.
Would you have any idea where I could obtain one of those.
thank you.

Often the Fujica bodies sell on eBay for less than $20. That cap seems standard for those Fujica bodies that have them. I doubt you'll find the screw cap itself selling alone and if you did it would probably be $10-15 anyway.

I know that a cap from an ST801 is the same.
