I have just acquired a pretty fun 1921 catalog for Harmograph Talking Machines (28 pages), which were made in St. Louis. It features pictures of the plants where the machines are made; material specs for all cabinets; motors, fittings, etc. for each model; ads for Harmograph records and needles, record albums and Bubble Books (the reason I bought it). It also includes a diagram of the motor and three pages of parts. I'd never heard of this phonograph before and don't know if any of the information in the catalog would be of interest to anyone else. If it is, just contact me off-list and I'll send along a scan of the pages you're interested in. Merle www.littlewonderrecords.com
