Choosing used textile apparel machinery means balancing stitch type, machine condition, and the work you actually run. Do you need a lockstitch for light leather and vinyl, a double-needle chain stitch for jeans and trouser seams, or a feed-off-the-arm unit for cylinder-shaped work? The four mechanical industrial sewing machines below answer different questions, and their listed prices run from $240 to $400.
Quick take
Let's be direct. If you need a one-needle walking-foot lockstitch for material, denim, light leather, or vinyl, compare the two Singer machines. If your operation is jeans, trousers, pants, or coat seams that call for a double-needle chain stitch, the Union Special 51-400 is the machine built for that stitch pattern. If you want a feed-off-the-arm Juki for cylinder work, the MS-1190 is listed as-is for parts or repair, not as a ready-to-run machine.

Product notes
Industrial Sewing Machine Union Special 51-400 double needle chain
The Union Special 51-400 is a heavy-duty double-needle chain stitch machine with a mechanical control and a two-needle head. The listing calls out 3/16 inch between needles and describes work on jeans, trousers, pants, and coats. If your operation needs two parallel chain stitch lines, this machine addresses that specific task directly. One limitation is that it is a chain stitch machine, not a lockstitch, so it won't replace a one-needle walking-foot lockstitcher. It is listed as used, so it brings the same condition considerations as any machine with prior shop life.
Vintage Industrial Sewing Machine Singer 151w3 one needle walking foot-Leather
The Singer 151w3 is described as a small walking-foot, one-needle, medium-weight lockstitch machine for material and light leather, with denim and vinyl also listed as suitable. It uses a 135x1 needle, and the listing is for the machine head only, so you supply a table and motor. This makes it a focused pick when you want a walking-foot presser to keep layers from shifting. The trade-off is that it comes from surplus stock and may need additional cleaning, and the light leather description points to lighter hides rather than heavy saddle leather.
Vintage Singer 151w1 one needle walking foot-Leather
The Singer 151w1 covers the same basic walking-foot lockstitch approach as the 151w3: one needle, medium weight, and light leather capability. The listing notes that the machine is complete and in good condition, but it comes from surplus stock and may need cleaning before it is ready to run. The practical difference between the two Singer listings is the model number, so your choice may come down to which 151w variant matters more to you. The same light leather and material range applies, which means this is not the machine for thick industrial leather.
Juki MS-1190 Double Chainstitch Feed-Off-The-Arm (AS-IS)
The Juki MS-1190 is a double chain stitch feed-off-the-arm industrial head, and this listing is explicitly for parts only or not working. It was damaged in shipment and is sold as a head only, with table and motor available for an additional fee. If you already run a Juki MS-1190 and need hard-to-source parts, this head could be a useful donor. If you enjoy repair work, it might also become a project machine. The limitation is clear: it is not in working condition, and the seller is not certain what repairs are needed, so it isn't a drop-in sewing solution.
Final recommendation
Pick the Singer 151w1 when you want a walking-foot lockstitch for light leather, denim, vinyl, or material. Choose the Singer 151w3 if you prefer that model number and want the 135x1 walking-foot lockstitch described in its listing. Pick the Union Special 51-400 when your work is double-needle chain stitching for jeans, trousers, pants, or coats. Choose the Juki MS-1190 only if you need an as-is feed-off-the-arm head for parts or a repair project. Match the machine to the seam it has to produce, and the decision becomes much clearer.
