What BB length for Sugino Impel cranks?

i never quite got to the bottom of what these cranks are,

my memory tells me it had the word impel and then a number before i started polishing but on the rear of the crank arms it said xd.

I think they are sugino 700. but anyways they took a 113 bottom bracket

1993 used a Fuse XD 500 with knowing Kona, some budget Shimano fitted ;)

1994 used an Impel 500 and would have had the UN-51 @113 fitted
 
As a side given it's 113 I would guess it's a Low Profile crank and not a Super Low Profile crank (i.e Shimno xtr/xt of the era)
So my guess is the range is 113 to 118, similar to Suntour MicroDrive

This is the range quoted by Sheldon Brown too...
