Quite right except both the HP and EP have mast torque wich uses mast twist to determine torque with a lot more accuracy than the "No P" and SP wich totalize the torquemeter from eng #1 & #2 as on the Bell 212.
The "412 No P" or "412 Straight" or "412 Classic" how ever you want to call it, is structurally very close to the Bell 212 not having the aft center fuel cell (five fuel cells in lieu of 10).
