Trying to find owner of 1951 Gold Flash FJG570 V5 April 23

[LaurieRocket3R]

My late father had a 1951 Gold Flash from 1951 till about 1960 when I was and 5.
I remember sitting on the tank for some pictures about then.
I have a picture of my mum and dad they took when on a tour of Scotland on the bike on my sideboard.
On my android phone I have an app that allows me to manage my car and bike details and search other vehicle details and MOT or TAX.
The app is vehicle smart.
I put on the reg of the Gold Flash FJG570 and he told me that a new ViC was issued on the 17 April 23.

App shows first registered 11Aug 1951
All other details as i know them.

I just trying to contact the current owner to maybe get a current picture and any history they may have.

Any help anyone can give me would be appreciated.
