Hey T Mar. I don't have a pic but I wonder if maybe this info is helpful,
My wife has a Landau in blue SN: CA 03998. It came to her possession with Suntour AR deraiileurs, Pro Vic II pedals, and a Silstar crank, It is designed by Norco with their usual "chrome molybdenum" crest on the upper seat tube.
Back of the RD read "MAEDA IND JAPAN XJ"
I assume that XJ is the date code and it would somehow match up with the 3,998th bike of 1981?
