http://www.kantamotwani.com/rdd2sukt Can you send me the date of production /introduction of Challange no 1 which I found in my cellar . Thanks for your reply HGThuemen.
see url Thank you for the message!
As near as I can tell the Challenge Series ran between the late 1950′ through the 1970s. I will take a look at the one in our museum to determine when it was made…if possible!
