Let's go with the MOM/DV6
This is the first Vader saber prop I ever saw back in May 1997. For many years I've considered it as the one true Vader lightsaber and it's still a very special prop to me, even since I realized how ugly and wonky it actually is.
I 've started to build my replica around 2020 out of a "Graflex Shop" flash tube, using the early template available back then to drill the screw holes. I also had resin parts found on Ebay, Wannawanga grips and clip, and various parts made from scratch at the time.
Then Wannawanga released his crazy DV6 kit. Many People started to build insane replicas out that kit, some were so close to the real thing that I felt discouraged: my unfinished replica couldn't stand the comparison so I gave up with it until recently, when a random guy on a Facebook page told me I absolutely had to finish it.
So here it is. Not the most accurate, I've made a few stupid mistakes I'm not gonna talk about.
I'm not done with it.
Wannawanga parts used:
DV6 shroud/D-ring emitter stuff/Ball-catch bearing
Grips
Kobold clip/D ring
While some of you try to replicate each scratches, grip angles and all, I don't.
I just distressed it the wild way, by leaving it in a bag full of stones and shaking it.
I also cut each T-tracks approximately without sanding anything. The idea was to get something that looked genuinely sloppy.
To emulate years of storage inside Lucasfilm archives I just droped it in my vacuum cleaner bag. That was my final touch

.
All my gratitude goes to Roy/Wannawanga who did an incredible job by replicating accurately the parts of that prop.
