Star Wars Figure Lot

PLEASE READ DESCRIPTION!!! Star Wars Figure Lot. I'm not sure what they are as I don't know to much about Star Wars. There are 4 figures in total. The bigger silver figure does feel like cheap plastic, I think he could be a copy. He has Hasbro SA LFL Vietnam written on the bottom of one of his feet. He does have lots of marks and scuffs on his helmet and silver marks on the inside of his cloak/ cape. He has a gun, not sure if it belongs to him. Chewbacca is solid hard plastic and his smaller than the other figures. Please see photos for full details as they are VERY IMPORTANT to all of their descriptions. All from a smoke free home. Thank you so much for stopping by and taking a look.
