The one in front is the Gen.1 the one in the middle is a Gen. 3 and the third is Gen. 4.I do not own origininal plasma's, nor bon, nor the later shiny plasma. I do however own X-Mans plasma and I really like it. It's about halfway in between original shiny second gen plasma and original X-metal.
The XX in the front is an original X-metal finish, the Juliet is an X-Man plasma. Hope this helps.

If i can preserve the matte bone finish and the serial I will do so if not I will sand blast the plasma off just like I did with my Half-X.
