Thanks for the pics Mark. Excellent quality. This faceplate deserves its own thread, but I don't believe that is an ESB faceplate. That appears to be a faceplate taken from a RB mold or family thereof. There are several features that do not add up to ESB, but point more towards ANH. I won't get into specifics because we all know we've had enough debates about these things over the years, so I'll leave it at that and, of course, it's just my opinion. It's still an awesome faceplate. It was a little tough to get these screencaps just right, but the only possibility I see of it being screenused in ESB would be this one:
In my opinion, there are a few details that match up. Nothing truly concrete, but some good similarities. The chin vent does seem a tad small for ESB. The positioning and height of the attachment ring would seem to be consistent with the difference in height and position of the dome in the Hoth scene.
In addition, I also see these few things that also seem to match up:
The missing paint on the side of the nose, but it could also be reflection of the light:
and the neck shape seems to be a good match, although I admit the screencaps aren't the highest quality to say for certain:
Again, nothing that is a 100% slam dunk, but pretty close from what I can tell. Thanks again for the pics.
Oh and here are the Baker vader helmets:
