Had the pleasure of adding this beauty to the collection, so I thought I would show some photos.
Soviet 23x260mm Case Telescoped cartridge for the R-23 Rikhter autocannon. Appears to be a Target Practice projectile.
Used on the Tu-22 “Blinder” super sonic bomber. Was very secret for a time until the Soviets exported the Tu-22 to Iraq & Libya. It uses a very unique forward loading revolver mechanism to feed a single barrel. Also is the only autocannon fired from a space station!
Super thrilled with this one, one of my holy grails! As such I made a little plexiglass stand for it.
