Metz 1910

Hello all, I have recently acquired a 1910 model AA from my Gramps who started to restore the car 20 years ago and purchased it 50 years ago. its was in many pieces and I am making great strides to re-assemble but I need help . the car is currently fire red but under the vehicle tags the color is a much deeper red almost burgundy. what colors were offered ? I will post some pics in the next few days . its an amazing car that as a kid I sat in and and now have the task of putting this gem back together and get my hero my Gramps in a parade as he has never herd this beauty run .
