Here are a few pics of my ESB blaster build. I bought parts from various sources before I decided to do a ROTJ Fett, thought I'd put it together anyway and sell it on.
Some parts required a lot of filling and sanding before they were usable.
All parts are resin casts except for the scope (real 4x20) and the 1 1/2 pipe. The pipe is used as a cheaper/lighter alternative to a MPP/Heiland tube. It can be removed easily.
Some parts have been primed, others primed and sprayed, just slotted it together to see what it would look like.
Will update later with finished pics. Probably end up in the cargo hold at some stage if anyone was interested. Not sure of price just yet.
