GP PAPS 22 mm mod AUGUST 2011 GP PAPS project began in Athens. The first prototypes had brass switches and top caps with aluminium tubes The first presentation with photos was on 15 September 2011 in the Hellenic forum, e-kapnisma.gr. In December 2011, George posted a video with a prototype GP PAPS on YouTube. JANUARY 2012 GP PAPS v0 came out with 303 SS welded tube, brass cap and button and circulated in Hellas and Germany. A few units have only 1 vent hole, while most of them have 4 in the tube and one in the button. 18350 was the default mode. FEBRUARY 2012 A full SS GP PAPS v0 comes out and it was sold in Athens and Germany. It was made from 303 SS welded tubes and had 5 vent holes. 18350 was the default mode. APRIL 2012 GP PAPS v1 released internationally, it was made from 303 SS rods, it had laser engravings, 303 SS cap and button all parts in polished and brushed finish and it was available via lists from Vaporwall forum. GP PAPS v2 follows soon with an improved button. During that period we created an extra size, the 18800 mode for a 18650 AW IMR battery + Kick. Both versions have C-clip to hold the button and they are made from 304 SS rods. It has 4 vent holes in the tube. 18350 is the default mode and only this tube was serialised. FEBRUARY 2013 GP PAPS v2.1 was made from EU certified 304 SS rods, it came out in polished and brushed finish with a new logo and the GP Telescopic Centre Post v2.1 instead of a hot spring, initially designed for the GP PAPS X during August of 2012. A nut was holding the button now. It had 4 vent holes in the tube. 18350 was the default mode and only this tube was serialised. Our logo was laser engraved. APRIL 2013 GP PAPS v2.5 appears in SS edition and LUX Edition and uses GP Telescopic Centre Post v2.5. The SS edition is made from EU certified 316 SS rods. The mod has a brushed finish and polished ends, it's able to stand upright and unlocked without firing, passing the drunken vaper test, as we like to say. The button travel is 0,7 mm. The LUX Edition has its own numbering, bottom and top caps from EU certified 316 SS rods and Aluminium Bronze tube, an alloy 4 times more expensive than the 316 SS. We used 25 mm OD Aluminium Bronze rods. The button and the telescopic post is 24 k gold over silver plated brass. Our logo is laser engraved in the SS Edition and CNC engraved in the Lux Edition. It has 4 vent holes in the tube. 18350 is the default mode and only this one is serialised. The threading from now on is calibrated and the precision is increased. DECEMBER 2013 GP PAPS v3 begins to be produced from EU certified 316 SS rods and it will be released in February 2014. In the previous versions, we produced flat top cap and crossed top caps. No need now with the redesigned crossed grooves, their ends conclude to 1 mm opening, which is visually less obtrusive. It has no vent holes in the tube. 18500 is the default mode and only this tube is serialised with a new numbering. The vent holes have moved to the switch and they are incorporated into the design of the button in a cross-like form. GP PAPS v3 will come out in SS Edition and Lux Edition. Both Editions will use the GPin, which replaces the GP Telescopic Centre post and any need for further adjustments for the atomizer and the battery. The locking ring has reverse threading from now on.
