Here is another custom Autococker with reverse gills milled into the top tube. I got this a few years back as a parts lot and have been slowly piecing it together.
This body has a lot of milling and is chrome plated, the frame is also plated under the black rattle can paint job but I am not sure if it was original to the body or not.
This cocker lacks a serial which leads me to believe it is another Jeff Orr mill job.
Although the sides may have been milled down I don’t think they would have been cut down enough to remove all traces of a serial stamp so I don’t think this body was ever stamped. I have another Sniper 3 which I know was a Jeff Orr mill job that I will post tomorrow or later today.
One neat feature on this body is the site rail has been milled further down into the top tube and then continuing into the back block.
Sorry for the bad camera phone pictures, this paintgun is in Northern California and they are the only pictures I have.
Also look at the Minicocker with gill milling I posted below:
