I have a Glenfield model 25 given to me by my dad when I was no more than 10 years old. I remember it like it was yesterday in the house I was born in. That would have been 1971. According to the info here from Brophys book the Glenfield model 25 was produced from 79-82. In 79 I was 18 years old and lived in another home so im sure it was 71 when I recieved the rifle. ???
