Unknown National 3/4 size, angular body, top tension Treadle

My wife and I purchased this recently from a couple that had gotten it from their mother in law. It measures 13" x 6 1/4" not counting the metal plate that's attached to the rear of the bed for the treadle belt. After 100+ hours of research this is what we have: National Sewing Machine Company made, 3/4 size body, (TT) top tension plate, stitch length regulator knob on the pillar, sharp edged Angular body (in 3 areas: both horizontal & upright arm and the raised area leading to the face plate). I have seen the center decal on a Velox VB-TT-3 on NeedleBar (VSM) and the undercarriage looks like the Vindex VB-TT-4 Home Queen on NeedleBar (both of these machines are fullsize). It looks very similar to a Paveway but it is angular (6 sides/hexagon) which means its not a Paveway. The irons and cabinet I have seen a few times from different companies, the pulls on the drawers I have seen on 1 pic so far. Its looking like a Frankenstein machine (all parts from different machines). Any other help is appreciated.
