My Fathers collection, only half the room too! has collected since he started as a volunteer 39 years ago

I wanted to show off my fathers collection, well at least half of it! I helped him redo the walls etc and I feel like this is what I can do to give back to him what all he has taught me throughout the process. He started collecting when he was 17 as a volunteer firefighter. and He just recently retired last year as a Captain for his Department outside of Columbus Ohio. My dad is an extremely honorable hard working man, and I am so proud of him for the lives he has touched through his teachings as a fire officer and the lives he has saved from harm.
