The devy parts are original Eruntalon. Ive looked at my own G1 and G2 parts.

Hotrod's gun , well mine has # 3 and next/ above to it has a little hole, the same size near the tip of the turret.

Fake Devy gun is straight unlike the originals (G1 and G2) which appears to have the 2 haves askewed where the halves are joined thus have a slanted level - slanting down to the right. Also the detailing is a bit bloated and less sharp with fakes. yours is sharp like the ones I own.

G2 Devys Hue of purple is lighter than G1. Fake Devy purple is darker than the G1 purple is and the gun tip of the fake has a more pronounced tapering at the barrel tip and there's some small holes on the gun part, prolly where the mold injection was ( for the fake)
