I, too, would have liked to have seen this before reassembling my 1903. It's one of the more difficult guns to reassemble. I have a tip that might make things even easier. I placed a couple of pencil sized, but powerful, magnets in the rear of the magazine well. They held the sear in the forward position and the magazine release catch in place while assembling the pistol. Squeezing the grip safety home and installing the pin was the real chore for me.
