Kellogg Wall Magneto Switchboard

This is a 1930s-vintage Kellogg 'Masterbuilt' Wall-Type Magnetic Switchboard that probably served a small rural community with its 20 lines (although it could serve more than 20 households via party lines). Thanks to Roger Conklin, Odis Levrier and Steph Kerman for telling me everything I know about this. This switchboard has a hanging 'bulldog' transmitter (it may originally have had an older-style, 'solid-back' transmitter) and operators headset. The Kellogg catalog at left shows a switchboard, the Type 30, very similar to mine except with a handset instead of the hanging transmitter and headset.
