Seeking late fathers blue series 3 - FBX290W

Hi there - I'm still looking for my late dads Series 3, pic attached. I know it's a long shot but any knowledge very much appreciated! It is now showing as SORN whereas from memory it wasn't previously. Also any advice on how to get round/through the DVLA to contact the current owner please! Thank you!

first stop you can do a history check, that will tell you if its been scrapped or not. with no available MOT data it will be hard to dig deeper in my opinion its 45 years old so went exempt 5 years ago, that means there would have been previous MOTs going back to around 2014 i think when things went digital, therefore its not been on the road between 2014-2020

To get DVLA information register as a car park owner. You'll get details no bother.
