I'm sure you're right, but the JX-26 I restored last year has handles,
and they appear to be original. The one I just got has holes in
exactly the same place, and sure look like they were there
originally. Is there a chance that some versions had them but
most didn't?

I have a JX-26 (R-274C) with handles. It is the only one of the 5 or 6
of these that I have with handles. I don't think they were add-ons, they
appear to have always been there.
