TOPIC: Looking for transom corner for Restoration

Looking for an original piece of rub rail for a Scat craft / Critchfield / sabre from 1971. I am missing one of the original cast aluminum transom corner pieces. Trying to do this as it came out of the factoryso not yet ready to settle for newer piece.

Have done lots of searches so far and am now apealing to anyone for a lead on where i might fiond one of these. Even a bigger stretch is I need the LEFT SIDE corner. Attached are pics of the RIGHT side corner, so the one I am looking for will be a mirror of this one.

This has a marking cast into the inside of it that says " NN15T"

15 T is th emodel of the hull. No clue what the NN is for.

Thanks for any and all ideas, thoughts and leads on this.
