A33Zab implausible with dual cartridges:
for the caracteristic of the SS the stronger spring must have space for the first 6.5 mm, (your nice picture is not exact in this detail) if the weaker spring was broken then the neutral aerea is between +/- 6 deg of handle deflektion.....
there are two dual cartridges so the risk will be seldom x seldom...... what is very seldom....
