...and some more bolts. Thanks Bacci for most of these photos.
Standard PMI length Better Bolt. Note the channel cut in the bottom to put backspin on the ball: Cooper-T Black Delrin PMI 1 Undershot bolt - 2.jpg Cooper-T Black Delrin PMI 1 Undershot bolt - 1.jpg Cooper-T Black Delrin PMI 1 Undershot bolt - 3.jpg Cooper-T Black Delrin PMI 1 Undershot bolt.jpg
Standard length EZ Pull bolts. Some with the larger thumb screws and one with the smaller variation. I would guess the smaller thumb screws were on his later designs. I see more of these bolts in NIB condition. Just a guess though, maybe someone else can chime in with more info: P-Series Cooper-T bolt.jpg Cooper-T P-series NIB.JPG Cooper-T PMI 1 bolt.jpg Cooper-T PMI 1 - 1 bolt.jpg
Same model in black delrin: Black Delrin Cooper-T PMI 1 bolt.jpg
PGP EZ Pull and an WGP Autococker Better Bolt. A General Joes PGP Centerfire Bolt is on the bottom. Not Cooper-T, but cool as well: Cooper-t PGP - Autococker bolts.jpg

What looks like a well-used KP2 EZ Pull: KP2 Cooper-T Bolt.jpg
This last bolt is for a Sniper II. Now, it's not anno'd red, nor does it have "Cooper-T" stamped in the back, but it definitely looks like his handiwork. Maybe someone else knows a little more about it: Sniper II - Cooper-T Quick release bolt.jpg Sniper II - Cooper-T Quick release bolt - 2.jpg Sniper II - Cooper-T Quick release bolt - 1.jpg
