| Stamp | Field | What it means |
|---|---|---|
| SE01 / SE02 / SE03 / SE10 / SE11 / SE12 / 2GS | Model | SE01 is the classic close-contact, SE02 the deeper hunter/jumper seat, SE03 dressage-oriented, SE10/SE11 mono-flap lines, and 2Gs the carbon-tree flagship. The model is the single biggest price driver on the used market. |
| 16 – 18.5 | Seat size (inches) | Measured from pommel nail to the center of the cantle. 17.5 is the most common adult size in the US. |
| 1–4 + A/C/L | Flap code | The digit is flap length (1 short → 4 long); the letter is the cut — A straighter, C forward, L extra-forward for long thighs. 2C and 3C are the most common combinations. |
| Year (e.g. 2019) | Year of manufacture | Used CWD prices track age closely — see our price-by-year data on the CWD price report. |
| Serial number | Serial | CWD (and many US reps) can confirm the original spec — and sometimes the original owner — from the serial. Always photograph it when buying or selling. |
TackTack's AI stamp reader identifies your CWD's model, seat and flap from one photo — and pre-fills a listing if you're selling.

Ask for a clear photo of the full stamp including the serial before buying. Cross-check the stamped spec against the listing (a '17.5 2C' stamp on an '18-inch' listing is a red flag). CWD can verify a serial number — worth doing on any saddle over $3,000.
Stamp formats vary by production year and special orders — treat this guide as the common convention, and verify serials with CWD for high-value saddles. Next: what CWD saddles sell for · shop used CWD saddles
