I have a question - were there any symbols associated with bastardry that a legitimized noble bastard was required or frequently did take as part of his personal coat of arms?

Arms don't work like that.

No. Bastards generally don't have arms, and if they do, they don't draw attention to their bastardry.

He's asking an historically based question, nothing wrong with that whatever the reason. We don't exactly have a heraldry board.

>Bastards generally don't have arms
Yes and no. Where heirs and legit children were typically granted arms descending (depending on the era) from their armigerous parent's, bastards could have them deviate further.

Was there any accepted pattern for a legitimized bastard to modify their arms, or was it on a case by case basis?

All heraldy is case by case. It's a myth that there's a set meaning to particular blazons. Some times there were reasons for the blazon aspects, but not always.

I appreciate your help, thanks.

Pic related, these bars in the middle of the shield (with various colors and patterns) were used in English and French heraldry to signal illegitimate birth.
