English: The tartan of the band (musicians) of the 42nd Regiment of Foot (Black Watch) used at least as early as 1780 through to c. 1865, and also used by the 93rd Sutherland Highlanders bandsmen from c. 1830s to c. 1865 (both later switched to regular Black Watch tartan for musicians). The pattern is Black Watch with the black replaced by red. Source: [1].

This image is not exactly full-sett, and cannot tile horizontally and vertically; this centred and very slightly zoomed-out version was created for tabular comparison to other regimental tartans.

Scottish Register of Tartans notes on this pattern: "An entry in the 1819 Key Pattern Book of William Wilsons of Bannockburn (weavers) reads 'To make the band or musicians Plaids you have only to put Scarlet in place of the Black in the Sergts Plaids.'" This is a usual, mirroring tartan. Thread count (in "/" notation): /B44 R4 B4 R4 B4 R32 G32 R4 G32 R32 B32 R4 B4/ (or in boldfacing notation: B44 R4 B4 R4 B4 R32 G32 R4 G32 R32 B32 R4 B4) This thread count is that of Black Watch (42nd) from SRT, with the black changed to red, per the original manufacturer's instructions. In a separate record [2], SRT lists this tartan with a somewhat different thread count – basically a mangled one with odd-numbered threads, and the blue and green proportions notably changed, such that the version has an unbalanced appearance that does not match what is shown in portraits, and just seems to be erroneous. If anyone wants it anyway, it is (normalized to standard colour codes): /B28 R4 B4 R4 B4 R27 G26 R4 G26 R27 B28 R4 B4/
