Darth Vader Lightsaber from Star Wars IV A New Hope.

Here is my model of Darth Vader's Lightsaber from A New Hope. This specific version is known as the "V2". It features a different clamp card and complete clamp versus the other Hero version that has a calculator bubble strip and a nail bent into position holding the clamp lever in place.

The actual prop was made from an MPP Camera Flash with the clamp card coming from a vintage calculator and T Track based grips from old cupboards.

I modeled this from blueprints and multiple reference pictures of original flashes and other props from the films.
