Leather would not look out of place on a graded Fox although, some may argue that for A/B grades... I have a A-grade project that I'll be putting a Silvers on. A friend has a Sterlingworth that has a red Old English and it looks very nice against the oil-finished original american black walnut stock. I believe Fox used to offer Jotsam Anti-flinch pads as an option that would have been a likely choice for a Sterlingworth, but don't think replicas are available today.
