Do you have a nutted spindle? If so are you measuing the stud? A pic is worth a thousand words, post a pic of the spindle with your calipers.
But in answer to your question Yes. The first two measurements pertain to your bike 36x24 would be Italain threading in a 70mm shell. 1.37x24 would be English at 68mm ( and some early MTBs with a 73mm shell) and the the third number is the spindle 36x24, 117 or 1.37x24 x 113.
Your crank isn't a triple is it?
