F-Pro refers to the standard mount used by B+W, a subsidiary of Schneider Optics, widely acknowledged as an excellent manufacturer of high quality filters. There have been some changes in the construction of F-Pro mounts in the recent past. The reference to "010" is synonomous with their coding for UV or Haze filters. "72" references the filter thread diameter, ie fits on a lens requiring a 72mm wide filter. More recently all F-Pro lenses apparently are at least single coated, as denoted by reference to a SC on the filter. Other versions are MRC or, for polarizers only, Kasemann (MRC with special handling). As Argyle noted, apparently your's are older uncoated versions. Generally, multicoated versions are highly recommended.
