Tartan ID help please

[AbernethyCameron]

Hi, hoping some of you knowledgeable folk can help ID this tartan please. I have tried all the usual sources but I have to admit defeat.

This is in good quality 13oz wool, with a really good selvedge and is an early Ann Higgins kilt dating from late 1960s or early 1970s. It fastens with internal fasteners on the left and a single long external belt that runs from the fringed apron on the right, fastening in the centre of the back of the kilt. Given that this is a "proper" kilt and is clearly a good quality weave I was surprised to not be able to ID it.

What looks like a white line through the green is actually a pale caramel colour and the red lines are deeper and less orangey than they appear here. This really has me stumped so would appreciate any informed views, many thanks
