Brother 1634DX Lock Serger

This is a Brother 1634DX Lock Serger, a specialized textile machine designed for finishing seams and edges with a professional overlock stitch. The machine features a primary white plastic chassis with a compact, tabletop footprint. Notable physical characteristics include four color-coded tension adjustment dials (yellow, pink, green, and teal) situated at the top, facilitating the management of a 3/4 thread configuration. The front panel displays the 'Brother' brand name in black and a decorative 'Lock 1634DX' graphic in light blue with floral scrollwork. It is equipped with a built-in trim trap to catch fabric remnants, a needle plate for both overlock and rolled hem stitching, and a metal presser foot. The unit appears to be in used but functional condition, with visible thread strands indicating recent operation. It is currently set up with four large spools of deep red thread on its rear thread stand. The construction is a mix of high-grade impact-resistant plastic for the outer casing and internal metal mechanical components. This model is a modern household machine (likely manufactured within the last 5-10 years) known for its ease of threading through lay-in tension discs and a color-coded threading system. No major cosmetic damage or structural cracks are visible in the photograph, though there is typical light surface dust and lint consistent with normal sewing use.
