ROTJ is a more straitforward bucket with redish orange kill stripes and no decals anywhere on the bucket, strait dirty metal earcaps. It also has a orange triangle painted in, unlike the ESB that has plain green triangles on the forhead.
The ESB has 5 key decals on it, on the RF ear it has verticl stripes in black, a circle with a t-shape, a odd triangle with two squares, and the famous white and blac half circle on the main earcap. On the other side there is a white half circle with a partial square with two dots.
The ESB also has a more colorful blend of shraches, I would consider it a bit cleaner then the ROTJ as far as "beat up" goes.
The Rangefinders are also different.
I will post pics at lunch illustrating this stuff.
