911S Paint 944/9/3

[Spey]

Looking for touch up paint options for the following:

944/9/3 (Platinum Metallic/Porsche Factory Painted/Glasurit paint PLATINDIAMANT MET )
76' 911s Signature Edition
I think original Porsche description, Platinum Diamond Metallic, and believe color may have been used ’76 Ferry Signature Edition Targa & ’77 911 Coupe.

Appreciate any assistance finding match to this color for a few front spoiler touchups.

Regards,
Christopher
