Gewehr 98 Loose Trigger Gaurd

[chbingle]

Hello all, I recently took my Gewehr 98 out to the country for some shooting. I have shot it before and have had no issues as its in very good shape; however, I now notice that the trigger guard area has become loose and appears to have lost a screw (can be seen in the middle picture below). I was wondering if anyone knows if this is something I could fix/replace? Thanks!
