You are aware the threads are rolled, not cut? That causes the major diameter of the threads to be larger than the original diameter of the spoke.
More likely you have 15/16 double butted like I use on my fronts and NDS.
AKA DT Swiss Competition.
Look for their logo on the end of the J bend.

What I'd do is replace the one spoke with whatever you can get and ride it for a couple months. IF you break spoke number 2, replace all of them on that side (at least) or both sides.
In fact I do have a caliper.
Middle .064 (16)
Ends .072 (15)
Threads I measured at .080. I thought that made them 14? Or does it still count as 15 because they were rolled out of 15 stock?
The spokes are from 1976. I'll check for a mark later when I can take a photo and enlarge it.

That's good to know. Maybe the one they put on the front does go all the way into the nipple.
