Searching For Crescent matboard

[GhostFramer]

A Customer brought in a piece to match and i can't find the right mat board color. We only carry bainbridge samples and I think the matboard might be a crescent (but crescent is of course on b/o on their samples for weeks).
Please help me find it or any suggestions on what I can order would be appreciated.
The mat is a solid core, close to SRM1089 (sauterne) but has a smooth finish.
please help
