Well that is quite bizarre - I am collecting bits for my B2/F3XC (also purchased from Niall) and I will have 737/739 and my wheels are the same as yours (except silver rims not red). Mine will have less colour overall - more silver with black highlights such as headset, bolts, seatclamp etc - maybe not this side of Xmas though :-(
Looking good though - a slightly different take on a classic bike
