Fire pin section of the Norinco TT Olympia pistol. (.22 l.r.)

SAFETY FIRST: When You take any kind of firearm in Your hand, ALWAYS FIRSTLY make sure it's not loaded!
This Video, on special request, shows the firing pin section in my .22 LR Norinco TT Olympa Pistol.
I've never took it appart, I don't know if it's made to take appart. When I got that pistol new (she was used and dirty) I gave her a good clean in the ultrasonic bath and oiled the firing pin with 2 drops of sewing machine oil. Since then I slightly grease the surfaces (swiss army gun grease, contains graphite) after cleaning the pistol.
Works fine.
