We have a couple 25 pounders (one normal, one as per funeral carriage) just 100 feet from my desk, so I walked over just now and snapped a bunch of photos of one handspike. I also measured this one and the diameter is 2.019, so there appears to be variation in the tube sizes. I'm guessing 2" tubing would be fine. I also found a pin holding the end cap on, and note the endcap appears to be brass.
Of the four handspikes in this location, one of them does not have rivets. I did not have a closer look to see if they are merely burnished flush or if the ends are welded on.
Here are the shots next to a tape. (the tape may have shifted a little in the second photo).
