Vintage Serpent Cobra buggy

[Orlinon]

I picked this up with another car.

I gave it a clean and under the grime it is in pretty good nick, albeit missing quite a few bits.
It's a Serpent Cobra buggy from the mid-eighties. I understand it is pretty rare. Any idea what it is worth?

I got on before less than 3 years ago, more complete than this and it cost me less than USD120 (shipping included) on the bay

Not worth much, especially incomplete. Far too niche to get much interets. But cool retro kit
