Pipeline Pedigree Help

[GunDogAdventures]

After running across some older posts regarding Pipeline dogs, I starting researching some pedigrees and have the following questions:
1) What grandsire behind Coca Cola Cowboy is nicknamed Sport? I see Mighty Manfred V. Highwater and FC Mastercharge.
2) Who is behind TC Wormenhaus, Drug Store Cowboy's grandsire on the bottom?
