The plot thickens! I just got this email:
Hallo Dean
Thank you for the message. When we had finished to talk, I remembered, that my grandfathers name was exacty the same like my fathers name and also the address. So it could be, that we were talking about my grandfathers gun.
Let's wait until the picture is ready.
Cheers,
Ralph
Ralph's father was born in 1933, and died at age 80 this year.
He would have enrolled at age 20, so 1953.
Then he would do 3 to 4 weeks every year until age 40, then 2 weeks every second year until age 50.
Jacob was in a machine gun crew. A few of the MG crew were issued rifles as well.
