English: The tartan of the 92nd (Gordon Highlanders) Regiment of Foot; designed in 1793 by weaver William Forsyth of Aberdeen. Also used by Clan Gordon, in this exact form, according to House of Gordon USA [1]; but this is not the same as a declaration by the clan chief. A variant with thinner black bands and with black guard lines added around the yellow over-check is also recorded as the main Clan Gordon pattern by Scottish Register of Tartans [2] (which isn't entirely authoritative either). Anyway, it is essentially the Black Watch tartan but with a yellow over-check on green in place of the single black over-check. The same or a nearly identical tartan (perhaps with a different-width yellow over-check) was also used by the 8th (Rothesay & Caithness) Fencible Regiment.

This image is exactly full-sett, and can tile horizontally and vertically. Scottish Register of Tartans notes on this pattern: "This sett has been recorded in a number of different places including the Cockburn Collection (held in the Mitchell Library, Glasgow), in 'The Scottish Gael' by James Logan (1830s) and 'The Clans of the Highlands of Scotland' by Thomas Smibert (1850)."

This is a usual, mirroring tartan. SRT-provided thread count (in "/" notation, and with SRT's non-standard colour codes for extra-dark colours replaced with standard tartan colours, if for no other reason than to make the pattern actually visible): /B32 K6 B6 K6 B6 K32 G38 Y6 G38 K32 B30 K6 B6/ (or in boldfacing notation: B32 K6 B6 K6 B6 K32 G38 Y6 G38 K32 B30 K6 B6).
