It doesn't I am afraid, but the chainset is deffo a Sugino XD 450 :

To measure it ( I can see you have taken both sides off, get a ruler, and two of anything with right angles on them: set square, book anything as long as it is small and you can set the base along the side of the ruler.
Tape the set square to that it's longest side is projecting at 90degrees from the ruler at the 10cm mark. This gives you a large set square.
Then holding it over the BB shell, place the long edge of the set square against one end of the axle, and set the other item, ( preferably another set square, but whatever works) against the other end of the akle making sure that it's bottom is flush and parallel with the ruler, and read off the length not forgetting to subtract the 10cm margin.

Hope that helps.

Oh or use a large G clamp if you have one, tighten it gently against the BB axle, remove and measure the gap.

I love the way the cat turns up just as he says he had a friend to hold the bike upright, as though it's about to do so.
