The following is Google translation of Fab's most recent post.

1901 for a Perfection, that won't be possible. The first model appeared in 1904. Model number: 7REE. It was equipped with a spectacle trigger guard.
Starting in 1906, on this model, the trigger guard was replaced by a standard trigger guard.
The Manufactory used S powder to proof their weapons until 1913.
The half-block barrels date from 1897.
The Hercules steel dates from 1898.
A few years ago, I went to the Loire Archives to consult the Manufactory's registers. During this visit, I took some photos of the registers for the 6REE, 9EE, and 344 models, all in 12 gauge. For the Perfection, 12 and 16 gauge, that's all I have.

Demi-Bloc or half block in the translation are chopper lump barrels.
