Um... hate to burst your bubble there, friend, but there is no Macross II VF-1R. The only fighters in Macross II are the VF-2SS, VF-2JA, VF-1MS and VF-1XX. The supposed VF-1R that you're thinking of is one of two things. It's the Harmony Gold interpretation of the Macross animation error, which has three head lasers on a VF-1A head, or it's the Palladium lineart of the VF-1 chassis with permanently attached FAST packs.
So you're either thinking of this (the art error from SDF Macross)

Or this... the palladium books concoction.

The page says it's from "Entertainment Bible 51: Macross II" but no such fighter ever appeared in Macross II: Lovers Again. The only fighters appearing in that series were the VF-2SS Valkyrie II, the VF-2JA Icarus, the VF-XX Zentran Valkyrie and the VF-1MS Metal Siren. (The fighter is also absent from the Macross Compendium)
