This is the Silver Knitting Machine Pile Rib Knitter, SRP-N. Image 7 shows a test knit, and images 8 and 9 are reference images docked with a Silver SK. The item for sale is only the SRP-N. Accessories include what is shown in the images, two types of cast-on combs, and a stitch transfer tool for rib knitting machines. Please contact Silver Seiko Co., Ltd. for compatible models. Instruction manuals, needle presser bars, etc. can also be purchased from the Silver Seiko Co., Ltd. website. I have removed rust from the pot as much as possible and replaced the needle presser with a gap sealing tape. If you plan to use it long-term, I recommend replacing it with a new one. They can be ordered from Silver Seiko Co., Ltd. Needles were also sold on AliExpress. I purchased this used last year, maintained it myself, and used it. I will include the test knit portion for your reference. Operation has been confirmed, but as this is an old item, you will need knowledge of maintenance, installation, and usage, either by yourself or a professional. I used YouTube and other resources to learn. I purchased multiple machines from the 1970s to 1990s to research knitting machines, maintained them, and used them. I am now selling it as I have a sufficient understanding of the structure. Please purchase with the understanding that while my maintenance is amateur, it may offer a little more peace of mind than an item whose functionality is unknown. Thank you very much.
