I am trying to sell a Left door side mirror and it came on my 230sl but I think it is the style of the mirror for the 250sl or 280sl? I have been asked if it is MB or reproduction? Since it was on the car when I purchased it , I don't know! The only marks are on the inside by the bolts and they are ..1-01-083... then L ( I assume for Left)? Does anyone know what they stands for?? Thanks Mary
