I am in the process of sending my H seat belts to Snnake Oyl for reconditioning. My belts are made from an off-white heavy weave material. The belts on my first H were black and made from a finer weave material. The belts on Jim Murdoch's H that is for sale are black while the belts that were on Gary Winthrope"s H appear to be the off-white ones. Which is correct? Are they both correct? Doug W.
