Optical grade prism from Uncle's WWII tank periscopes. This one is 2-1/8" on the hypotenuse, 5-3/4" long, and 1-1/2" on the leg. They may have small non-interfering chips or surface scratches. These military tank prisms will be gone one day soon. That will be sad. In the meantime, get the unsilvered version, they make great rainbows.
