C. 1979 SHERIDAN Model C Blue Streak. 20 AIR PELLET RIFLE

  
This a vintage Sheridan Model C Blue Streak pellet air gun. It's a 5mm or. 20 caliber, which was only used by Sheridan. They are still readily available online. Serial number is C 1791F which I believe indicates it was made in 1979. Walnut wood stock in excellent condition and is the blued steel receiver and blackened brass barrel. Gun is complete and functional but won't pump-up to make compression. Interior seals need to be replaced. Many places offer this service.
