I called the phone number that Mackaydon posted and had to pick a person to talk to.
Osterud is now Home Federal Investment Department.
She knew of Red-John Osterud who owned Osterud Insurance and he is past away a long time ago.
I told her about the badge and she thought it to be very old.
I will keep looking for imformation on this badge.
That looks like a "fire mark" Insurance co would pay a premium to the first volunteer company that would show up. it would be displayed on the front of a building
