Nice Kenmore, Robert!
Just so happens that I have a copy of the 1935 Sears Catalog, and this vacuum is shown on page 526 as their top model, selling for $35.50 cash with your old cleaner, or $39.00 and your old cleaner if paid monthly. They also offered, on the same page, the Standard model at $26.95 cash or $29.65 if paid monthly (either way with trade-in), and the economy model at $17.95 with your old cleaner, cash only. Attachments were not shown for any of them, but they did offer the Kenmore Junior hand vac for $9.95, also on the same page. AND, on page 594, two non-electric models are shown, at $9.50 and $10.85 respectively. Sorry I can't help with information on the manufacturer, but would assume it's Birtman, as they built for Sears for quite a few years.
