Christmas Carols Quintet Music - older Richard Price Arrang

[Danzon01]

I was given a set of Old Handwritten Christmas Carols arranged by Richard Price from 1980.
However it was missing the entire 2nd Trumpet Book.
Does anyone know how or where to get a hold of these arrangements?
Songs Include:
Away in a Manger
Carol of the Bells
O Come O Come Emmanuel
Deck the Halls
Ding Dong Merrily on High
God Rest Ye Merry Gentelmen
Good King Wenceslas
Here Comes Santa Claus
Santas Comm'n
Silent Night
We Wish You a Merry Christmas

Thanks
