Appears to be an adjustable spark gap. The two metal fins, one connected
to
each horizontally opposed points, are the inputs. The third point would be
connected to ground.
Yes, I think that it's a spark tester for small engines but then someone
questioned this and said they thought it was used with radios. Do you think
it's for radios, small engines, or both?
