Devices included in this entry:

Beckman SP-332 panaplex (2-digit bathtub, pictured in thumbnail)
Sperry SP-333 panaplex (3-digit bathtub)

The SP-332 family of devices are tiny, seven segment neon Panaplex displays, built to a digit height of only 7 mm. The SP-332 has an identical internal layout to the larger and more common SP-352, though takes up only half the volume. Sperry also manufactured a three digit display in this form factor, the SP-333, which is a miniature version of the larger SP-353. This was a prolifically produced family of parts, with identical versions of each part number being produced by Sperry, Beckman, and Babcock.
