Have to say C&V on Bike Forums is absolutely the best. I was contacted by another member today who has a 170mm Sampson crankset like the one on the bike. My dad is definitely interested so the deal will be done. I also have the torque specifications from Sampson. My dad was really impressed that I could get some resolution this quickly (gotta admit so was I). Just another reason I spend 95% of my time here at C&V.
