Highlighted in this articles is an unidentified Stainless Long barrel Nelson based pump drop in kit that was put on an early 007 pistol. This kit likely dates to around 1987 to 1988. This came in a lot off ebay in July 2018.
I bought this pump and another nearly identical set up that was configured for constant air. My first thought was this could have been assembled by South Bay Arms and be hardchromed steel but after examining this marker it is stainless and not hard chrome, which leaves me wondering who might have built it?
The stainless unibody / barrel kit is constructed from three pieces, the outer body, the barrel and the feed. The body is braised together and is certainly well done by a skilled airsmith which makes me think this may have been a commercially available product, or the person who made these produced more than the two pictured in this article.
The seller was out of San Tan Valley, Arizona and these paintguns originally belonged to the seller’s dads friend “Jager” who he was told constructed the bodies. But did Jager build these Nelspots or only assemble them from parts?
There was a sear in a small plastic bag from PX Paintball which was an east coast manufacturer / distributor but I don’t know if PX Paintball offered these Stainless kits?

I don’t think I have seen any other stainless barreled Nelspots dating this far back so these are definitely an interesting find.
The pictured loader is a cut down oil can loader, possibly an early Ram-Box (pre molded version) sold by Rambo at Sat Cong Village prior to the intro of the WGP Ammo Box.
The pump installed on the in grip valve Nelson is a piece of PVC. The feedneck has been very nicely braised on, frame, (early needle piercer/non cup) in grip valve and hammer are stock Nelson.
The frame is also earlier style with the small 12 frame changer screw.
Steel Bolt features a ramp to prevent pinches / chops and is not anti kink. It is either aftermarket or homemade. Another bolt that matches came in some spare parts made out of stainless.
Pump handles became the norm in about 1985 on the west coast and scratch built long barrel bodies for both Nelspots and Sheridans first showed up in 1986 and were becoming standard in 1987. An assortment of WGP ammo boxes (introduced in 1988) were included with these pumps.
The loader on this pump is likely homemade but is reminiscent of the early Ram Box loaders made by Rambo at Sat Cong Village. It is built from an oil can and glued together and then covered in camo tape.
