G'day Jack,
Thanks for fixing the dating timeline for these SS mowers and for all the work in adding all the Mower brochures etc.
Yes that one above is correct Jack ,the link above has C1975 and I had you correct that one also by
pointing out the production date is listed in the text.
What was strange in the 1971 SS brochure is the lack of vertical start Kirby motors shown in the brochure.
Cheers
Max.
