Don't know which one it is but the Starfire name was applied to double cutaways at least as far back as the '60's. Perhaps it is only because they never made a single cutaway bass and called it a Starfire but I have to look at labels before I remember that there are single cutaway Starfire guitars
That is a Starfire V. You can tell by the block inlays and the bigsby. I have however seen a guild bigsby on a Starfire IV in the past. The Starfire VI is like a V except with gold plated hardware, ebony fretboard, and a 3-piece maple/walnut neck. Starfire I, II, and III have a single cutaway.... but you should really just get the Guild Guitar Book.
