In the beginning Maufrance used a numerical grade system.
1888 to 1899 it was simply 0 through 8 for black powder proofs and 9 through 13 for smokeless.
They changed it in 1900 to all smokeless and the most commonly found system, the 2R, 3R, 4R type designations. As the numbers get higher the quality gets better. That grade type designation lasted until 1930 with some slight changes as the years went by.
From 1930 until they ceased production in 1985 Manufrance used a 3 digit model numbering system, always beginning with 3.
If you want more specific information, please post the question. Even though I'm pretty up to speed on Ideals, I find it too complex to remember the system except in general terms as above. I use a detailed chart when I want to identify a specific gun and where it fits in the program.
