Very nice. Beautiful case colors. Keep it out of direct sunlight and do not subject it to harsh chemicals because they can cause the colors to fade.
No turn line. To avoid getting a turn line, never lower the hammer from half cock. If the hammer is lowered from half cock, the bolt will rise and be pressing against the cylinder. Any subsequent motion of the cylinder will cause the bolt to rub against the cylinder, which is what causes a turn line. Always lower the hammer from full cock, which keeps the bolt engaged in the cylinder locking slots without it pressing against the body of the cylinder.
When loading, set the hammer to half cock, load one, skip one, load four more, close the loading gate, and bring the hammer to full cock and lower it carefully. An empty chamber will be under the hammer. Practice doing this a bunch of times until it becomes second nature.
That's quite a collection of old 45 Colt ammo. I have a couple of boxes like the ones on the left that I bought back in the 1970s. Not sure when the other boxes were made, but none of it is new.
By the way, you done good on the3 price.
Your Colt is a 3rd Generation. The 3rd Gen started in 1976. In 1978 Colt changed serial numbers from the 2nd Gen SA suffix to the SA Prefix. Early 3rd Gens did not have a removable cylinder bushing, it was press fit into the cylinder. Later they went back to the traditional removable cylinder bushing. Is your cylinder bushing fixed to the cylinder or is it removable? Just curious.
