Just got mine from vaportekusa, on the caps on mine, the spring on the bottom cap, and the bolt head on the top cap are both golden/brass in color. Doesn't necessarily make them brass, but they are the correct color, lol. Your spring appears to be silver in color. I emailed vaportekusa when I ordered and was told they have replace springs with proper ones. Guess time will tell. Good luck.
Anyone know what version this is ? It said #1 when I bought it. Is this and updated version of the 8 ? I noticed it had the sigelei stamp on the front if that means anything ?View attachment 223670View attachment 223671
