Here are some photos of my data plates that were taken from a Morane-Saulnier Type P during the war by a US soldier. I obtained them from his grandson but he had no information other than his grandfather had brought them back from the war.
If anyone has any information of any kind on the aircraft from which these plates were taken I would very much appreciate hearing about it.
The first is the main data plate. The fields read:
Note that the first number uses a letter 'I' as the first punch mark followed by the numbers 533.
I am not sure why there are two number fields, but my guess is the second number is the sequential number of the Type P models that were built which would make this plate from the 408th Type P of the 565 total type Ps that were built, while the first number might be a serial for all Morane production.
The accompanying data plate from this same aircraft is its speed warning plate. It reads:
'La vitesse du régime maxima ne doit être utilisée qu'à la montée; dans aucun cas elle ne doit être dépassée. Dans le vol horizontal on ne doit pas dépasser la vitesse du régime normal afin de diminuer les chances de pannes.
As best as I can translate this with my poor 'Frenglish' this loosely says as:
'The maximum power setting should be used only when climbing and in no case should it be exceeded. In level flight do not exceed the normal power setting in order to decrease the chance of breakdown.'
