Thanks all,

That's really interesting, I had no idea but it makes sense now.

By the way, when I say tunic, I mean Highland Tunic as per the label. It is a 1912 dated scarlet doublet with yellow facings.

I've checked my tunic and there's really no evidence of the buttons being switched. As GS buttons became standard, is it not actually more common to find one with GS buttons than without?

As for the sporran part of my question. Has anyone ever seen a GS sporran badge?

Thanks.
