Figure was made by a friend, I did the accessories. It's a Mainframe body with Prowl head and Shapeways accessories. Includes rifle, shoulder cannon and giant pencil. Perceptor Action Master Weapons by mathewignash on Shapeways
Very nice. If I remember correctly Perceptor was among a number of G1 characters who were going to be included in the Actionmaster line up but got cancelled. Other cancelled figures included Ultra Magnus, Superion, Bruticus and Predaking. There was a website years ago called Custommasters that made dozens of Actionmaster customs that might interest you. Your Perceptor is excellent by the way. You should get his buddy Blaster for him.
