Calamity, I looked at Franklin machines on line and if your feet are not back clamping, but are low shank feet that connect by a screw on the left side, you should be able to get a walking foot from: shop.sew-classic. The walking foot I use for my Singer 66 should work for you. It is the Straight Stitch Low Shank Walking Foot. Works perfectly for my treadle. It is made to work with narrow feed dogs which is what these older straight stitch machines have. You could phone them before ordering just to check. They are super helpful. Good luck.
