Bunnell Double Speed Key.
These keys from the early 1900’s were perhaps the most popular swipers used by commercial ops on Great Lakes freighters. Prized now as antiques. [W9OK].
Home made Gold cootie key.
The last of several configurations on the way to a swiper with a good feel... Gold-plated, 1x3x4-in. brass base, gold contacts. To retain stiffness yet allow suitable flexibility, the armature is of triple-thickness thin brass stock, except for about an inch of single thickness at its mounting post. Knob is of rosewood... A sweet to use! [W9OK].
