Blastech E-11

The standard sidearm for the Stormtrooper is a Blastech E-11.
In the original film A New Hope the prop department made the E-11 using the Sterling sub-machinegun as a base and attaching a lot of "greeblies" (a word apparently coined by the production team meaning bits and pieces glued on other stuff), making it look like something out of another universe.

An original Sterling before anything was added:

I recieved my blaster as a kit with all the pieces molded in resin from an actual blaster, something that made me have to assemble it myself and paint it afterwards, but having it look extremely accurate once finished.

Considering blasters (and all things proprelated) people have the opportunity to make them as screen-accurate as they want, for example in the one hand we have people buying toy blasters that are similar to the screen-used ones, but lack much of the detail and require a lot of modification to be accepted as a sidearm in the 501st Legion, On the other hand though, we have individuals opting to track down real Sterling machine guns that have been demilled (can't be fired) and affixing them with the real parts that the prop team did, using miscellaneous military parts, as a M38 scope used on a tank, a Hengstler counter and other parts. Stuff the prop team in 1976 most likely found lots of and cheaply, but nowadays is extremely expensive (most likely because you have dedicated propmakers outbidding eachother and inflating the price of said items).

Good thing there is a great community of propmakers that make resin casts of original parts and sell them to others striving for accuracy, but don't want to ruin themselves in the process!
I started out my build to get a feel for glueing and building stuff again, all the while documenting my build over at FISD.

Here is my kit laid out:

A few weeks of glueing, tinkering, drilling, filing, sanding, tweaking and building an inner bolt 

(note my helmet in progress behind it):

Primed and ready for paint and subsequent weathering, to make it look used:

Voila, it's finished!

I now have a screen-accurate E-11 blaster at a fraction of the cost of a real one, but it has taken some time and couldn't have been done without the help of the FISD, lot's of reference photos (like this awesome blog: Sterlingblasterconversion), and last but not least the opportunity to attend TK-8505s armor workshops with loads of tools and materials.
