I at first thought it was MacLachlan Red Modern. But upon further inspection, that's not even close.

This tartan seems to have a rather large sett, with the black stripe only going through the center of every second red strip.

The tartan in the first photo is "78th Fraser Highlanders Pipe Band". They commissioned a custom tartan based on the regimental predecessor.
Where can one find this tartan? I don't see it listed in any of the normal databases.
