Vintage Metal Sears Kenmore Zig Zag Sewing Machine Model 158-13410 Has been tested and is working! I used this to sew a few garments. This thing is metal and a tank. I just have another newer sewing machine with more stitches, so I no longer need this. Good vintage condition. I’m including extra bobbins and the manual for a similar model that’s really useful for learning how to operate this one even if it’s not the exact same. You can find digital scans of the original manual online if need be. Let me know if you have any other questions or would like more photos!
