Looking for Ducati Bevel 900 SJB 731Y

Hi All,
I’m trying to find my old beloved Bevel 900 street fighter, built by me from scratch in 1981 and subsequently sold to John Fallon, it’s been taxed in the UK so I know it’s still alive! I’d love to hear from the current owner, if this is you, please get in touch. I’ll try to attach an image below if it works!
