My sister in-law lives in her grandparents home. She was digging around the basement and came across a receipt from a attorney for $25.00 for a patient on a coil tester. So she googled it and this is what she came up with. I never met him but I was told by family members that he was a very smart man. And loved to tinker. We do have documentation and pictures of him flying and working on airplanes
Can anyone tell us about it? Or have any pictures of one?
