This is something I made originally way back in 2007 ( http://www.donjarrs-place.com/07-making-stuff-sw-proton ) and based its design on screen grabs from the film, and sized it using the vent on the side, which was also used for Darth Vader's reveal helmet and Dengars chest piece, so by having it allowed me to get the size as near the film used one as I could get.
This comes as a kit which needs painting and assembling and has instructions included on how to put it all together. You get everything you see in the first two pictures, so apart from your choice of paint nothing else is needed. The main body however is hollow cast so for those with knowledge of adding electronics if you want you can add a rotary switch to the main knob and LED's so it's even more like the film one but that's up to you.
I have also included a couple of pictures of one I fully finished so you can see what it looks like when done, and also stuck to the freezer with magnets which are included.
The bulk of it comes in beige resin, but also includes red LED covers and waterslide decal stickers to apply to the outside when done.
