My first 9W-7 came in a 5 drawer treadle cabinet with the pull out center drawer with the cut outs for the accessories. The four side drawers have filigree on the front and the side bars are curved and decorated.
I've got the cabinet apart making repairs. This pic shows the parts I've fabricated to replace those that were missing:
This pic show the broken off bottoms of the outer edges of the facing:
What I need are clear photos of a good example of this style of treadle cabinet and measurements from the top edge to the bottoms of the outer curved parts.
That would help a lot in my fabrication of the replacement parts.
I've looked at all the Singer cabinets ISMACS has, and none of them match this cabinet.
