File:Smallest Prince Charles tartan, 19th-century colours, centred, zoomed out.png

English: "Smallest Prince Charles" tartan also known as "Prince Charles Edward Stewart - 1819" (spelled "Stewart" in this case). This is a "fashion" tartan designed by William Wilson & Son of Bannockburn in the 19th century; it is a variant of "Royal Stewart", with even less red than the "Prince Charles Edward Stuart" pattern. It keeps the even-sized thin overchecks of RS (PCES does not), but alters various of the other proportions subtly from RS, not just the red. This tartan is not to be confused with "small Stewart" or "small Stuart", another name for PCES. There's no evidence this pattern is used by Clan Stewart/Stuart. It dates to the 1819 Key Pattern Book of Wilsons.

This version of the image is in colours that approximate the appearance of the original sample, which may have faded since 1819; and is not exactly full-sett, and is not tileable horizontally and vertically. It is a centred and zoomed-out version, for comparison with other tartan images given the same treatment. Scottish Register of Tartans does not have this sett in their database. I got it from tartanologist Peter Eslea MacDonald in his role as the maintainer of the Scottish Tartans Authority database, who got it in turn from a surviving Wilsons pattern book.

Like the others in this group of tartans, it is an asymmetrical, non-mirroring sett. STA-provided threadcount, in "..." notation: ...BR32 A12 AK18 Y4 AK4 W4 AK4 OG26 BR16 AK4 BR4 W4... (where BR = basic red, A = azure, AK = ancient black, OG = olive green).
