Sgt Fang Darth Vader Helmet

can someone explain to me the big differences between an ESB darth vader helmet and an ANH darth vader helmet.

I was thinking of picking up a darth vader helmet from sgt fang, but they are ANH and I was hoping to do ESB


is it convertible? maybe simply a lense and paintjob difference?

any experts help would be appreciated

I think the most obvious difference is the ANH "widows peak" in the front of the dome. ESB doesn't have it. Other Vader-heads will know better.

The peak, the lower mouth section size/shape, dome mount, and the paint (finish, colors and scheme) are the primary differences.

PM sent for some more info...
