Will,
One other indication for the correct action spread (112.5 vs. 113.5mm). If the let off dowels are angled it is pre 1992 (112.5).
If the dowels are at 90 degrees it is post 1992 (113.5). Since yours is neither pre nor post 1992 perhaps this information will help.

  The only question for me is which of the two values given by YC it should be.
