I've had a couple of questions about how to difference arms when the usual conventions cause problems or would be unclear. I've prepared two examples:

1.


In this case (and correct me if I'm wrong) the Stodart system would divide the bordure per pale with a colour denoting the son's birth order. However, this leads to the breaking of the "no metals on metals" rule (as the dexter side would be Argent and the sinister side would be Or). How would one deal with this?

2.


In the second case, the "question shield" would (and again, correct me if I'm wrong) have the bordure split as above. In this instance, both sides of the border would be Gules so the bearer's arms would be identical to those of his father and eldest brother. Would the sinister half be chequy Gules and Argent? Or is there another way to show the bearer's place within the family?

I apologize if some or all of my assumptions are off-base; I admit to having limited resources on the subject.

Thank you, once again, for tolerating all of my questions!
