Kobo H2O aura repair

[Hitchar]

Hi all,

I've bought a (broken) H2O aura from a second hand marketplace. I bought it from someone looking to repair it with a new screen from China, which he already bought. But he never finished the repair, so I got it for next to nothing.
The thing is however:
On arrival the four screws for the metal frame are missing. Has anyone any ideas what size those are, or how I can find replacements?

Thanks in advance!

assuming the screw holes are not also missing, they should provide a clue !
trial & error will work, eventually, if you don't get a better answer

also you may want to just hold it or blu tack it in place and check it works, before fretting about the replacement screws

pm me if you can't figure it and I will check if I have them, or identical. Unfortunately I almost never throw stuff out!
