Fantastic Grant,Id heard snippets of a model 31 but Ive never seen one.I knew their must have been another model between the "Spin" and the 35 since their was maybee 2 years I couldnt account for.I was sure the 35 didnt start until around 59-60,please correct me if im wrong:)This is really something quite unique.Pity its not for sale.Thanks for the Images Grant,youve pretty much fit the last model to the SB rotary puzzle!Awesome:)
