so theres nothing written or stamped inside the grips.. whats that mean?

I just picked my wifes brain a little about the guy who gave it to her.... he was late 60's 35 years ago... she doesnt remember his last name but his first name was Ed. He was given the gun at his retirement party from "remington dupont" she said... but i think she is mixing up two companies. But remington must have bought the gun to give to ED for his retirement. If it really matters i could ask her x and see what he remembers about "Ed".
