Rare Vintage Singer Tucker: Sewing Machine Attachment Part No. 161226 for Slant Needle Machines
What a find! If you own a Singer Sewing Machine model 301, 400, 500, 600, or 700 series, you must have this time saving tucker attachment. There is a difference between the 301 Slant Stitch Tucker and this Slant Stitch Tucker #161226 - the needle hole is larger to accommodate zig-zag and decorative stitches.
