My reading of your bolt picture is that the number is a badly stamped “9” which could be taken for an “8”.
Given that you’ve clarified that the rifle serial begins “60” and not ”80” as per the scope mount it’s worth checking what’s been entered on your FAC to ensure it shows the correct serial number. You don’t want any issues arising with your local licensing dept at Police Scotland!
P.s. the link to the earlier thread about the rifle was interesting. The 2013 photos look very like the staging/style of a UK dealer based in SE England(Kent?).
