Newest addition to my "Boys Rifle" collection. This is a CJ Hamilton Model 27 , 22 short and long, 14 3/4 bbl in pretty rough shape. JGB these gun were produced between 1906 and 1930 in Plymouth, Mich. Known as tip ups because the breech breaks like a shotgun made from blued stamped steel. Stock and forearm are made out of a flat birch boad with slightly rounded edges and stained with a walnut colored oil. This is and example of the "later model" produced after 1907 and since there were no serial #s the year of production is lost forever.
