The gun was given to me by my father in 1954. My 1st gun at age 4. Originally belonged to my grandfather. Shot it with .22 short std velocity as a boy.
By the mid 80's was in need of repair. We knew a pretty good gunsmith who agreed to fix it if we agreed not to shoot it. So in operating condition, but has not been fired in many years.
I grew up 1 mile from Plymouth, worked on the P.D. there for 28 years, and still live just a few miles away. Those rifles were probably made at the old (now torn down a few years ago) Daisy BB Gun factory (previously known as 'The Plymouth Iron Windmill Company circa 1880's). Clarence Hamilton was the designer of Daisy BB guns so it's very possible that he also most likely built those around the same time they were producing the BB guns.
