This is the info, that I have :
total produced 59 :
49 LHD and 10 RHD
or
32 4doors and 26 6doors + 1 SWB (=shortened LWB)
1 LHD LWB longsofttop Landaulet in september 1965 for the Pope Vin 000362
1 LHD shortende Landaulet in 1967 for the Count von Berckheim Vin 000830
4door presidential : 10 = 9 LHD + 1 RHD
6door presidential : 22 = 18 LHD + 4 RHD
BUT this is according an official overview from the factory , that not fits with the numbers of pictures .....
There are pictures from a 6door RHD landaulet short softtop converted with a W140 motor in (Malaysia) that never was produced conform their production-overview .....
So if you get more or better info, LET US KNOW ....
