Trying to track Volvo fh 12 version 1 460

It was my fathers old truck it was exported as far as I know the reg is 00 Mn 1369 white cab 4x2 I would like to buy her back

That’s it

I think the term needle in a haystack springs to mind. If it was export it would be on different plates now. I guess the reg number you have quoted was Irish? About the only way of tracing it would be with the chassis number but even then…
