Field by field

Stamp	Field	What it means
P / M / C	Seat depth	P (plat) is the famous flat seat, M is medium, C (creux) deeper. Butet doesn't use model names — the seat letter IS the model, and P-seats are the most sought-after in the hunter ring.
16 – 18	Seat size (inches)	Stamped next to the seat letter.
1 – 4	Flap length	2 is standard; higher numbers are longer flaps. Forward-cut variants add a letter.
Year + serial	Year / serial	Butet's Saumur workshop can trace a serial. Premium grades (full buffalo) command noticeably more used.

What the stamp means for value

P-seat Butets hold value best — check the P-seat rows in our Butet price data.
Butet leather is soft and marks easily; honest condition photos move these saddles fast.

Authenticity checks

The stamp should be crisp and shallow — deep, uneven stamping is a warning sign.
Ask for the serial and verify the seat letter matches how the seat actually rides (a 'P' should look visibly flat).
