Hi all, I'd like help identifying this puzzle. I know it is a Ghosthand puzzle because it was my main when i walked away from cubing years ago & i remember it being phenomenal then but it feels genuinely terrible compared to today's hardware. There was a version I, version II, and 2003A produced according the wikipage. This was most likely purchased this from Cube4u circa 2008-2009. Both the edges and corners feature a single cap that pops off to reveal a hollow piece.The edges corners and centers all have stamps in the plastic that say "(GS)" on the top and a number "1", "2", "3", or "4" on the bottom once the center cap is popped.
I plan to give this cube a face lift by applying either Cubesmith supercube stickers or some custom Cubsmith shades i have that only fit older puzzles. I regret taking the original stickers off to make an F2L only cube because the original stickers had such a retro and faded look that i wish i could recreate.
Any ideas what it is? Bonus, what lubes work well with this plastic, you can see all the old residue most likely from RC car diff fluid.
