Here are some views of Ruger's very first product - the Ruger "Red Eagle" Standard .22 LR pistol. This particular gun was made in the first full year of manufacture - July, 1950.
This is the left side of the pistol. Note that the Ruger emblem in the grip panel is red. This was later changed to black when co-founder Alex Sturm died. Note that the rear sight is "blocky" and fit a 1/4" dovetail, rather than curved. The safety is smaller than in later manufacture. The muzzle had a curved crown, rather than flat.
This is the right side. Here you will see that the ejection port is not beveled as it was in later manufacture.
Here you will see the pistol field stripped into its five component groups - the barrel and receiver, the lower receiver, the bolt, the mainspring assembly, and the magazine. The entire bolt was left "in the white" rather than being partially blued.
Here is the pistol as it was originally shipped, in the box with papers and early advertisements clipped from the American Rifleman.
Here is a view of this pistol compared with Ruger's latest version, the Mark IV. The outline has not changed much, but the internals differ a lot, particularly with the newer takedown system.
I thought you might find these detailed views of interest. This was the gun that was the beginning of the huge company that Ruger is today.
