Electrolytic can oddity

While working on my V-M 307 stereo phonograph, I pulled a can-type electrolytic capacitor from the power supply. The V-M 307 uses a transformerless power supply with a voltage doubler for the B+, so the capacitor can is hot with respect to the chassis. The capacitor can is insulated with a cardboard wrapper.

The circuit uses three stages of filtering, with 80 µF, 40 µF, and 20 µF sections. But when I pulled the wrapper off the can, the can is marked for a two-section capacitor, with two 80 µF sections. Perhaps V-M special-ordered the caps and the manufacturer modified a stock two-section design.

Has anyone seen this oddity before?
