Based on your picture, I will venture a guess that it is MOST LIKELY strome. Here are my reasons:

1. The twill is running /// NOT \\\ (which is consistent with the 'face' of Lochcarron's Strome)
2. The tuck selvedge on the bottom (not kilting selvedge)
3. The slight waviness and apparent 'softness' of the cloth in the picture... a Stome 'trademark' (the way their cloth drapes and feels a bit softer compared to other mills)
4. The light green and light blue appear to be consistent with their color pallet of blue and green (as opposed to other mills who use a darker light green and a darker 'light blue' for their ancients)
5. You ORDERED Lochcarron Strome, so your kilt maker should honor that request and use the mill you specified.

Just my $.02
