This is a super nice Sliding bolster auto made in Russia! The parts were made in the 1970's and sat on a shelf in a warehouse until they were purchased and assembled by a craftsman in Russia. Mint condition. Coil fired spring. You simply slide the top front bolster to the right and the blades fires open with authority! Mirror polished clip point blade. No blade play whatever in the open position and sits deep in the handle. Green and black acrylic inserts. Top bolsters are stamped with the Russian double eagle. Bottom bolsters are stamped wit a likeness of St George (patron saint of Moscow) slaying the dragon. Comes with a certificate of authenticity.No more will be made so if you have been wanting one this is the time to pull the trigger!
