Colin Thompson’s Verti-Flow Anti Siphon System

Pictured in the video above is what Erick Lambarri dubbed the Lapco “Verti-Flow” System.

Erick purchased these two stocks and several other parts from Colin Thompson around 1997-1999 at “Colin apartment in Mira Mesa.”
Erick says:
“Verti-flow is the name I gave [the Anti-Siphon tanks systems] when I asked [Colin] if he still had them. He liked the name.”

Paintball Connection first opened in 1991.
Earlier this year when I was asking Colin Thompson about Paintball Connection he wrote me:
“In 1991, I moved from LA to San Diego to set up a manufacturing business to build the guns. John Seivers funded it.”

Erick first met Colin at Paintball Connection in Mira Mar between 1991 to 1993. He remembers seeing the Verti-Flow system mounted on paintguns (Ghosts? / Spirits?) during this time.
“The [setup that fits inside] the stock I saw on a gun. The other screw in [dual tank Verti-Flow was setup] on a matched bottom line so it would screw in and be vertical.”
“I think [the Verti-Flow setups] were made 89-92. [I] didn’t think to ask what the dates were on the tanks.”

Paintball Connection closed sometime between 1993 and 1996 when John Seivers and his wife Becky lost interest in paintball and were overwhelmed with John’s district manager job at Western Dental.  During this time Colin was working at Paintball Connection and living with John Seivers and Thompson told me the news of Paintball Connections closing was unexpected and meant all of a sudden he was out of a job and a place to live.

Erick Lambarri drew this illustration to show the proper setup for the asa mounted stock.

Erick explains that “the vertiflow with the stock would be mounted on the grip frame of a gun and you’d run a hose from the valve to the asa on a gun.”

Another drawing from Erick to illustrate the proper stock mounted “Verti-Flow” setup, upside down to Anti-Siphon Gas for consitency.

Erick also points out that “The stocked [Verti-Flow] is upside down in [the] video. [Both setups were] meant to get air not liquid.” He went on to write that “The tanks were meant to be upside down with the tubes pointing up [to act as] anti siphon [systems].”

Verti-Flow Dual Co2 stock mounted on a back bottle early Lapco Grey Ghost. Stock pictured upside down since as pictured it would act as a Siphon tank and reversed it would act as an anti siphon.

Another neat detail Erick noticed is that the end of the anti siphon tube is made from another of Colin’s products.
“What’s funny is if you look at the ends of the brass tubes, [Colin] used the brass thumb screw heads on the end of the tubes.”

Thanks to Erick Lambarri for the information on these tank setups and the quick sketches on proper mounting.
