The reference books SDH mentioned above are: "Winchester's New Model of 1873, a Tribute" by James D Gordon, 1997. This is a really fine two volume hard bound plus a soft bound volume three book set.

A much less expensive alternative might be "Winchester Lever Action Repeating Firearms, Vol 1 (Models of 1866,1873 and 1876)" by Arthur Pirkle,1994. A quick skim did not show the .22 in any significant detail.
