Digital Odometer,92 300se W140

[92300SE]

Thanks for the answer on my previous questions,now I have
a general question related to the standard equipment on my
92 300se w140:I have all the books,no window sticker for the
car,so,its hard for me to figure out what optional equipmet,if any,
was installed in it?
1.I have a digital odometer,I noticed most of the 92-93 models have a mechanical one,was it optional?
2.Is there any way to obtain a copy of the original sticker with
MSRP AND OPTIONS?(this car was purchased new in Indiana,in
october'91 as one of the first w140 ever build/sold in US...)
