Carl,
I remeasured the cap, and the two sections are 17-63pF and 24-316 pF, pretty
much what I had measured before N years ago. A single section cap on the
same frame would be 379 pF, or maybe a smidgen more since there would be
coupling between two plates that are separated in the dual-section version.
I used a good quality cap meter and compensated for the lead capacitance.
