Rear View Mirror for a 56

My 51 never had one which I can understand with the divider in the back window but with the 56 with its solid glass in back I am surprised there isn't any and no sign of there ever having been one. Was a rear view mirror offered as an option in 56?

I have one in my 56 S-120 4x4

I have one from a 56, you can see it in the 56 owners manual pic

contact me if interested
