Not the delta hinge, the fact that the blade angles forward from root to tip when viewed side-on.

Starter interlock - keeps the starter from operating if the rotor isn't turning
and the clutch is engaged. If there is pressure in the MRGB, the starter will operate no matter what.
>What is the function of the slat?
*** stability during autorotation. stops the nose dropping
Yep, but how?
>Will it fly at 320 RRPM?
*** 320?! you mean 3200??
320 rotor RPM (green range is 390 - 504, power on is 442 - 471). BTW, that pic is from a CB or CBi, note the 2530 - 2700 ERPM range.
Whirls, 300C models will have two tanks to go along with the left-hand PIC - let's put it this way, I've never seen one with only one tank. The CBs and CBis often only have one tank as suits their training role and RH PIC setup. You can option LH PIC and dual tanks on a CBi, but at 1750 lb MGW you will not often be able to put more than 35 gal into the tanks with two people, so it's of limited utility. The 300C has 200 or 300 lbs more useful load (depending on when it was built), so it can usually go full fuel (up to 64 gal).
