Tartan of the Month - June. What do you see?

[Morris at Heathfield]

Well, I see the Greek letter Φ rotated 90 degrees. I haven't a clue what the tartan was used for, but the pieces look like leftover scraps to me.

Regarding the tartan itself, SlackerDrummer's interpretation of it looks generally right to me, except that the black stripes (not the tramlines) should be noticeably wider than the adjacent red stripes and the green pivot stripe. If it's a registered tartan, I haven't been able to identify it yet.

I suppose I'll hazard a few guesses:

Use: scraps left over from ?
