With such a seemingly strange name, Silver Pile Rib Knitter is simply a ribbing attachment. Although I have not tested one myself yet, it looks very similar to Silver Reed (also known as Singer and Studio) SRN-321 ribber, on which I wrote a detailed article already. Thus, Silver Pile Rib Knitter is compatible with the following knitting machines: Silver SK301, SK302, SK303, SK305, SK 311-SK315, SK321- SK326 (and potential higher model numbers), Studio 305, SK301, SK303, 312-315, 321-326 (and potentially higher model numbers), Singer MemoMatic 321, MemoMatic 322, mod. 323 (and potentially higher model numbers), Empisal KnitMaster ES-302 and ES305 as well as Empilsa KnitMaster 321, 323 and 324 and Riccar RK-601 and potentially other models looking similar to the machines mentioned above.

Refer to the pictures below as I look for more information on this attachment. Keep in mind that pictures below do not show a connecting arm.
