Here are notes from the guy who sold it to me:
__________________________________________________ ___________________________________
Vintage Sheridan Custom KP Paintball Marker.
Custom made from Ohio based maker of the Hardcore paint markers featured in APG magazine.
Includes Cooper T bolt, carved stock, velocity adjustment, direct feed, ball roll retainer and constant air.
There was a tournament team called “Capital Punishment” in the mid 80’s
until the ninety’s. They were mostly police officers, military and
engineering folks.
They built guns like this out of PMIs and KP3s. Teams at
the time dominated with these guns. The were advertised in 88 and 89 in APG
magazine. The version they sold was called the “Hardcore” same basic
features but instead of the wrap around grip it kept the side feed tube as
a swab holder and they had a peg to pull back. They sold for $450 at the
time.
One cool thing about the bolt. It is designed to lock the bolt in and
not loose pressure when shot. These were commercially available. They honed
the inside slightly to speed up the bolt.
Bill I can’t remember his last name (Will let you know if I remember) built this gun custom for me with
the wrap around grip to lighten it up. At one point I had an aim point red
dot sight on it… until hit.
I played against them at a tournament outside
of Chardon called “Pinnacle Woods” not sure if they are still open. Bill
lead Capital Punishment and I was part of “TNT” the Nissan Team.(local
dealer sponsored.) Also played back yard ball with them.
Back to the guns.
I ran a 7 oz tank but some ran 20-33 oz tanks with extended custom barrels.
Like I said the guns ruled the area until the auto mags and auto cockers
came. Great bunch of guys but the last time I saw them was 25 years ago and
then they were late 40’s so not sure where they ended up. I miss the old
guys from back then, Vietnam vets with nicknames like “Chopper” and “Jinx”.
I figured I should pass it along now.

This is not frozen or gunked up. It racks easy, holds pressure, and shoots at 310fps+ with Co2.....
Once I find out what it is worth, I'll put it up to trade for a comparable valued AutoMag/MiniMag/MicroMag...
