Hi there, welcome and Well Done!
What a great present to give, especially your own time for your father.
Google cannot find an LF-2001 Ducati jacket, sadly - that era clothing though is right between the Foggy and Troy Bayliss years, typified by the style below I believe?
I do have a similar style of two-piece somewhere but mine is the Corse Style and more White with a little red...
Good luck; Ebay and Gumtree are prime - I did know of a recycle shop in London but it seems they might have folded.
