An Overview:

In The second film of the original trilogy We see a very different series of designs used to equip the actors during scenes.

 

We have 3 distinct types of e-11 for this installment.  First is the Resin cast version of the e-11 with several added features that were not seen in any other version.  In some instances the blaster is used by snow troopers, yet also is seen with regular troopers in promotional shots and other locations.

 

Other versions of the blaster were seen on screen and have a basic variation.  The M19 scope is usually cited as the ESB version, yet the M38 scope is also seen on screen.

 

The london prop store creation has not been screen matched, and seems to be a mocked up version.
