This p blocked minicocker with reverse gills showed up on ebay last month and I missed it. Ended up finding it listed on the custom cocker forum 3 weeks ago.
The original owner who sold it on ebay wrote me that he played on Team Secret agents for 5 man and Team Turbulence for 10 man.
He also wrote the milling was done by Jeff Orr.
The gill milling is the reverse direction of Predator Gills.
I added the OTP barrel and will likely be parting this and then rebuilding the body with different pneumatics and a polished or chrome frame.
Edit: I’ve leaving this Jeff Orr Minicocker as is and not removing parts.
