Notice that the reeds of this Pianica are affixed to the air chamber cover, rather than facing it from below. Consequently, the reed plates of the P-32 and the P-32D are roughly mirror images of each other, with the same spacing between reeds. The P-32D shown here is missing its low end reed plate.
Here, the P-32 on top, P-32D on bottom.
The tiny strap also helps date this model as 1960s.
