I inadvertently bought a Buster Prime from the Prime/Jetfire 2-pack without realizing that he has the standard Leader Prime face plate. The paint on the face plate head is awesome, but what I really wanted was the original Buster head sculpt with the exposed mouth. Is anyone interested in making an even exchange? I'll pay for shipping. PM me.
So, you have the original Buster Prime? I would have no way of knowing. As far as I can tell, the only difference between my 2-Pack Buster Prime and the original release is the face sculpt. I don't think the blue would be any different. They're both produced and released by Takara. If you would like to take a well lit close up a pic of yours and post it, I could try to verify this.
