Tracing origins of a Technics sound?

This is more about a sound than about my KN7000 but couldn't think of a better place to post.
I have a sound in the edited sounds section called Mellow Horn or Mellow Horns.
A brilliant brass sound which suits playing Elgar etc.
I had this sound before I got my KN7000 so it could have been used on my KN6500 (most likely) or my AC1200 module (unlikely).
As I have bought loads of software, I don't know where this sound originated and wondered if anyone is using the same sound and knows where it came from.
My KN7000 is now in storage (due to a fault on midi out) and I am back to my AC1200 module and trying to get all my favourite sounds back together.
As Technics sound are not backwardly compatible, I cannot load a sound from the KN7000 into my AC1200 but must use the original disk which creates a problem when I don't know which disk it's on.
It may be that the original sound won't load into the AC1200 anyway if I did get it with KN6500 software but I have to try as I will miss it so much - used it a lot in Christmas carols etc.
Hoping someone else has it and can enlighten me as to it's origin.
Quite a challenge this one but thanks if anyone can help.
