Sperry Ignition Analyser cursor.
Hello, this is my first post.
We fly & maintain 2 x P2's + a L1049, all of which require reference to the ignition analyser for serviceability, functional checks etc.
During my RAAF days, we always carried a cursor to place on the oscilloscope screen to check the 20 degree & 25 degree (27 on the Connie) ignition Retard & Advance positions. Would anybody have a spare one of these, or alternatively a template for correctly manufacturing one?
Many thanks.
