Mine was bought second hand about 25 years ago. It was my first airgun and a Christmas present from my parents. It is stamped IJ38 Made in the USSR. Fantastic design with adjustable breech for wear, barrel lock and bear trap. All steel sights and stock had nice pistol cap and spacers. After I bought mine the lad next door got one. It came with spare leather seals and spring.
Mine was very accurate considering the cheap 'Champion' pellets I used to feed it. Still works fine today and no plans to sell it.
