It seems to me that I’ve been ignoring the words ‘again and ‘make another’. Putting in my best guess for each and we get this:
3: and then bring the point towards the ground, that is with the false edge of your sword towards your brochiero and strike your brochiero with the false edge.
4: Then throw a high upwards cut with a mandritta and in this cut you do a molinello by making a gran passo forward with the right foot towards the left.
5: Then make another [molinello?] with the left foot and go over the brochiero and strike the brochiero with the pommel of the sword on the side inside the rim.
6: Bring the sword hand forward and place the sword point towards the ground and then bring the right foot forward and cut with a montante.
7: Again [montante?], with the foot towards the left and ending in the guardia alta and your brochiero extended.
8: Now cut with a fendente against the rim of the brochiero with your right foot back and the blow to the left against the right. End in the coda lunga e distesa.
In step 5, using a molinello on the right lands the pommel on the buckler in a most pleasing fashion.
Step 7 is troubling me a bit, so I’m turning to dall’Agocchie for a hint. He often uses two cuts with a single step. If step six is a montante riverso then you can flow that into a montante dritto.
The montante dritto from alta is an interesting cut to me. With a finger over the ricasso the cut is worthless. But use an early style grip and it is surprisingly powerful. Every cut against the pell landed on target and much harder than I intended.
