Viking indeed made slant shank machines. A quick search turns up
"-These models have the older unique Viking slant shank: Models #1+, 1250, #1, 1200, 1100, 1090, 1070, 1050, 990, 980, 960, 950, 945 & 940; all of the genuine Viking snap on feet will fit, there is a specialty screw on walking foot still available. The ruffler is no longer available. Generic feet will not fit these models."
