The Singer 316G was made in the Karlsruhe Germany in the 1960s. They’re a different breed of machine from the 206, 306, & 319 series of machines, and don’t use the 206x13 needle system. I have a 1960 Singer 216G zigzag treadle that was an earlier model to the 316G, also made in Karlsruhe. It takes 15x1 needles and class 15 bobbins. My machine is missing the bight lever stops that control the zigzag, so I’m probably going to have to make something to replace them.
That 316G could be treadled, and would sure look nice setting next to my wife’s Singer 401A and 301A machines of the same color. And unlike the 206-series machines, the motor boss on my 216G accepts a Singer hand crank. The treadle that mine came out in is a cross between a coffin-top treadle and an industrial stand. The top is 18 inches by 36 inches and has no extension leaves.
