Sorry to hear about your brother's poor judgement. Glad you found one to function as your "memory" item for your father. For those of us who shot a lot with our dads growing up, these are very close to the heart.
Luckily in my family, my father knows between my brother and I who will keep the heirlooms and who will not. Hence the reason his Highway Patrolman now has a permanent spot in my gun safe when it is not out galloping at the range with me.
