Finally got my hands on a reasonably priced Master Replicas Force FX Vader ESB lightsaber. I wanted to have it on display as just the hilt so today dismantled it and removed the blade; and as it's a DIN style plug it's easy to plug the blade in again if needed, and stays in pretty well.
It needs a bit of TLC as the clamp was scratched trying to remove the retaining pin, and I had to cut the pin as it would not come out. It's also got slightly sticky grips, which seems to be a common problem, so may need them replacing too.
Just need a stand for it now as the FFX stand is too wide. For now it'll sit on top of the case for my ATA Works ANH helmet alongside my Doopydoo's heavily modified E-11 blaster.
I'm also looking for a DIN style plug in LED if one exists so it still has the option to light up without the blade, but all I've found so far are conversion kits which require swapping out the blade holder section; I'd rather keep it as original as possible. And I'm eyeing up a Rubies Deluxe Darth Vader helmet as a cheap helmet to display with the lightsaber, but after getting a so called "deluxe" First Order helmet a few weeks ago and finding it's too small and needs a lot of work to look even passable (luckily it was cheap, about 1/2 RRP here in the UK), I'm not sure if the Rubies is worth the hassle.
