victoriansweatshop.com is a great resource for Singer 101 issues and questions. I have 3, an aluminum in bentwood, one in the first version cabinet with cross brace, drawer and oil can door, and one in the version 2 cabinet, no cross brace. Both with the medallions in the front legs
YOur cabinet is interesting, in that it accepts a full size bentwood case. I believe these were called combo tables. I have one that accepts a 3/4 size, 99 or 128, although the 128 needs some shims, as the base is shorter than that of the 99.
