The second keyer has had Heath SB-Line knobs and feet added.

The differences in the front panels are just a progression of design changes.

I have two Hallicrafters HA-1 keyers and each has a slightly different front panel and type of knobs. I need some opinions on whether the HA-1 ever had the type of knobs shown on the second keyer (description to follow).
