The Eclipse is the name of the patent, which has been invented by a french dentist, in 1935 !!
Peugeot has used this patent, and finally has bought it.
It has been applied on 4 different models (301, 401, 402, 601) from 1935 till 1938.
I haven't found the global qty produced. However, as a luxus vehicle in 1935, it should be very confidential.
