Dean,
Here's a couple pictures of a Winchester Model 67 Boy's Rifle. It has a 20 inch barrel, 11 1/2 inch LOP and 33 1/2 inches total length.
A simple single shot .22 bolt action that the shooter manually pulls back the bolt to cock the action. Normally found chambered for Shorts, Longs and Long Rifles. Winchester made the Model 67 for the .22WRF also but pretty rare especially in the Boy's Rifle. Another rare variation are the 67's with smooth bore, no rifling, for .22 LR Shot.
