The top diagram that Frank shows is for an early TR2 which came with those two spring thingys and the pull cable shown over to the far side with the pull knob at the end for the driver of a right hand drive TR2. Also if you look closely at Frank's diagram, you will notice 4 cooling slots which are shown at the top back of the panel. I am led to believe that these only appeared on early TR2s.
In addition to the 4 holes you are asking about, do you have 4 air outlet slots across the back of your bonnet ? Other TRs only have two slots here.
If so, then I can only assume that your bonnet is from an early TR2.
