Here are some excerpts from a Model S eBay listing which may end speculation of whether the Model R began prior to 1960:
"The Manual says it is a 'Special Model'".
"The Manual says it is the World's Lightest Weight Heavy Duty Cleaner. There is writing on the back of the manual it says - Paid in full 69.75 +tax =72.19 Nov. 3 - 1960."
Wouldn't this prove that the Model R was launched not long prior to November 1960--say October?
