While my giftee is no longer involved their prompt was illuminated manuscript with a kneeling Dunk (amazing line up with my own offer), and I knew just the Codex Manesse image.

Though the 'plot' veneer here is after Ashford, Ser Arlan's coat of arms (with the black diamond of a funerary hatchment) gets a top spot as part of Dunk's lineage.

Dunk's arms are simplified to be a little more real world heraldic.

The Targaryen arms are not the show version again for real world heraldry - where the important part is a consistent blazon (written description) rather than a absolutely consistent image. So unless the dragon was specified as in annulo (in a circle), these are can still be described as Sable, a thee-headed dragon Gules.

The little arm beasts are also Dunk & Baelor. I like to imagine them curled up together like the weirdest little cat things.

Dunk-beast is pointing specifically at the 'hold honor in their breast' line as an "I remembered my vows, did you?"

The helmet Baelor is presenting has the Targ color torse (fabric twist) as livery for a knight sworn to the house - the similar twist on Dunk's arm is absolutely his King's ✨favour✨. Winged crests in shield colors were very common in Germanic heraldry though it also double up here as a trace of Ser Arlan again.

Baelor's little cape has a pattern called vair which is supposed to look like a squirrel's winter fur. Royal mantles and all that.
