Do you have a map ref for these buildings Olly, I was at Barneycraig mineshop, Scraithole mine and other bits around there a few weeks ago and didn't notice your range of buildings, having said that I wasn't looking for them either. Are they on the main road and in Carrshield itself?
Edit:
There is a High Blue Row at NY 804469 on the 1890's OS map on the NLS website.
