Provenance
James Logan recorded the MacLachlan sett in 1831, on page 406 of the Table of Clan Tartans in The Scottish Gaël — the earliest systematic published collection of clan setts. Logan gives the stripe widths in eighths of an inch, measured across the cloth and reflected about each end (a half-sett):
4 red · 1 black · 1 red · 1 black · 1 red · 8 black · 8 blue · 1½ green · 8 blue · 8 black · 8 red · 1 black · 1 red
In threads (at 8 to the eighth-inch) that is R/32 K8 R8 K8 R8 K64 B64 G12 B64 K64 R64 K8 R/8. Logan named his colours rather than dyeing to a standard, so the palette here is the Dictionary's modern reading of his names.
See Logan's Scottish Gaël for the full table and method.

Later records of the MacLachlan name adjusted Logan's counts: MacLachlan; MacLachlan #2; MacLachlan #3; MacLachlan #4. Compare their thread counts with Logan's above.
