Their appears to be some confusion about the orientation of the Belt End of a Clan Crest.

There are many examples of the belt end draped over (towards the viewer) and many showing the belt end tucked under the standing part of the belt.

It has been posted here that the belt end tucked under signifies "The Order of the Garter" but I can find no definitive proof of this.

Romilly Squire's designs use the belt end over the top, but The Court of the Lord Lyon shows it tucked under.

Does anyone have, and can provide sources, for a definitive answer?
