its a Diana 5, an early one, very nice, good shooter.
Silicone oil only if it has a leather piston seal. Proper would be to remove the end cap(CAP UNDER SPRING PRESSURE!! ) pull the piston,moly the sides of the seal & lube the spring(Maccari black tar) And might as well replace that +40 year old piston seal too if your gonna shoot much.
