That is the correct instructions but that is NOT the Revell kit. The cockpit is a seperate section in the Revell tooling, and split vertically with very good detail throughout. As opposed to the Italian attept with its complete fuselage split horizontally, and poor attempt at a cockpit, which is clearly seen on your WIP. Trust me i have multiples of both kits in my stash and at work!
As i recall Revell have not reboxed the IDS version of the Italeri kit, only the ADV, which as you mentioned also has been done by Tamiya-3 in my stash!
If you bought this new and unopened with that kit inside it I'd very much not use that shop again!
