It looks more like a Franken'ed GGTS. A Rev 1 has no collector tank and AD features. Rev 1 has the old style 4-in-1 cap which connects directly to the top tube w/o any adjustable draw features or connector piece. Also, the bottom cap looks to be from the 2012 version.
If you ask on the GG thread, you'll get a clearer picture from the fanb.., I mean, enthusiasts.
you hoseiliao... !!!
ok spoke with a person that was compiling GG products history list, showed him some pics and it was concluded what i owned was an old batch Rev 3 ggts that had a separate listing for serial numbers at the gg wiki.
And omg those clones really look like the real thing! Cheers~
Lol... dun be so harsh lah bro...clones are still clones, you will find it hard to resale
