Frigidaire weird part

[bajaespuma]

This ad claims that this is a GM Frigidaire 1-18 pulsator diaphragm in an unusual color. The years don't seem right but I wanted the Frigidaire people on this site to know about it.

The label on the box is from Feb 1971, these were made for the 1-18 rollermatics - the years are correct in the auction. Frigidaire also made these same translucent pulsators for the earlier rollermatic machines as well, easily identified by the "D" shaped hole on the top.
