I went on the Dalgleish site this morning and they have it listed in 13oz and 16oz... but I don't know if they carry it in stock.
They call this colour scheme "reproduction" rather than "weathered".
It would be interesting to see kilts made from Lochcarron "weathered" and Dalgleish "reproduction" side by side.
