Arten Olympic - lost a screw! :(

[Kyuudo]

Howdy folks, sorry if this has already been answered, but I did a search and couldn't find it.

I've lost a tiny screw from my Arten Olympic sight - the one on top that you loosen to make large windage adjustments. Well, I loosened it a bit too much and lost it in the grass . I can still shoot, but my site aperture tends to rotate gradually.

Here's where it used to be:


I remember reading here that Arten went under a while ago; I've also read many times on these pages that they used to have incredible customer support, but I guess I'm a little too late for that.

So... anyone know where I can get a replacement, or the size/thread of the screw so I can find a replacement myself?

Cheers.

I have some spare parts for an Arten sight. I don't know it's name but it is very basic. It has the screws that lock the windage adjustment. I am not sure whether those will fit all types of Arten sight.
Someone may know, so they might help with that.
Also, if someone knows the thread size on the Olympic, I might be able to check the one I have to see if it's a match.
