It is perfectly possible it does not have a name beyond the code.
It looks to be a variation on their highly prized Thistle collection.
Thistle, Iona and Star of Edinburgh are their "flagship" cuts, their most famous and are never contracted out, while other cuts have been.
I have always looked out for thistle cuts and I have not seen this particular one before.
I have seen plenty of the Edinburgh one, fewer of the Tudor and the Svarc ones.
