...  and by 1941 had settled on the 12SA7, 12SK7, 12SQ7, 50L6, 35W4 (or equivalent Loctal or miniature tube) circuit with few modifications.

This is a Philco, so it has 7A8, 7B7, 7C6, 35A5, and 35Z3, but an AA5 in any variation is the standard from ca. 1941 on. For a design with only 5 tubes the AA5 provides reasonable reception at a low price. I can't see it commanding $1300, though, especially because it is not a Catalin cabinet. My most expensive radio cost far less than that at a local auction (a 14-tube Howard 425A) and greatly outperforms any AA5, in addition to including features such a beautiful wooden console cabinet, remote preset tuning, and a 15" Jensen speaker.
