Devoucoux saddle decoding

[Xanthoria]

I have two saddles I’m comparing here - can anyone help? I’ll ping the rep if not:

Saddle 1:
Makila Lab
16S17011040
Arcade Normale
17.5 2A
FG D8D4+

Saddle 2:
Makila Harmonie S
23S44044934
002 2A
D3D 40 3+ 10
Block V3

From what I can tell the have the same seat size and flap length. Saddle one was made in 2016 with a regular tree, and saddle 2 in 2023. But the bolded parts are what I’d like to know.

Can anyone help please?

Does anyone know how to decipher this?

D3D means the panels were cut with a laser so they are symmetrical (allegedly). 4.0 (or 40 or 4 or 4-0) means there is nothing added to the front of the panel.

3+10 means there is 10mm of foam added to the rear of the panel to lift up the back of the saddle.

4+ on the 1st saddle just means there is a build up in the front of the front panel (think super either clearance for a TB type).

Very very different saddle panels.

Thank you!
