Hello, new member here, and I can help with your question.
A green version didn't officially exist, but what happens is that during production, the hoppers that hold the various colors of styrene beads get changed out and/or refilled. There's a transition period where injections are made to clear the old colors, and these parts are then minced and recycled (usually into control handles). Some yellow and blue were mixed at some point, because this green variation was the result. These parts were then passed along for assembly, either deliberately or by mistake. You can scrub away as much as you want to, but it's still gonna be green.
My greenish version is an early 70's model, and has color swirls in hte 'blue' parts, similar to what your stabilator has.
Hope this helps.
