You’ll have to read the text to find out what this is…

Here’s a question for you: what is this that is pictured above?  Take your time; I’ll wait…

Got it?  Or not?  Anyway, it’s the trigger assembly from a Winchester Model of 1905.  The Win ’05, as it is commonly termed, is a long-recoil autoloading rifle developed by Tom Johnson and introduced, presumably, in 1905. Now that you know what it is, here’s a second question: why is it the subject of a blog post here?  After all, we’ve never done anything on the Win ’05.  Take your time to answer; I’ll wait…

It’s here because it’s the direct ancestor of the US Carbine, Cal..30, M1.  When Winchester did their “Hail Mary” to finish a design for the Army’s Carbine competition, Ed Pugsley’s team pulled together ideas and designs from several sources.  One obvious crib was the bolt and op rod design from the M1 Rifle.  Pugsley and his men decided to use “Carbine Williams’” short-stroke piston to actuate the op rod and bolt.  Finally, in the interests of expedience, the team took their Win ’05 trigger assembly (shown below) and used it pretty much whole hog, pushbutton safety, mag release button and all.  But wait, this is a 10/22 blog post, isn’t it

You’ll see the rest of the story in “The Ruger 10/22 Complete Owner’s and Assembly Guide.”  When Bill Ruger designed his .44 Carbine he put his own twist on the Carbine trigger assembly.  Later, the 10/22 trigger assembly simplified the .44’s, but the design still can be traced back to the Winchester Model of 1905.  Now you know “the rest of the story.”
