Specs, credited to R. Gustafson, ran 5/12/46 – 5/25/47, not every week of course because it was a filler. This could, I suppose, be Bob Gustafson, but I assume he had his hands full at the time assisting/ghosting Tillie the Toiler for Russ Westover.
Shaggy ran intermittently 10/7/45 – 7/11/48. It was credited only to ‘Gould’. I think I’m safe in guessing that neither Chester nor Will were involved.
