Lost: Tank Accessories near Stuhr Museum, Grand Island

I was packing up after a family day at the Stuhr Museum of the Prairie Pioneer in Grand Island on Saturday around 8:15 PM when I realized my Tank Accessories weren't in my tote. The items were in a black, weathered plastic case with a red zipper, the kind you put spare treads and tiny decals inside. I walked from the parking lot toward the museum entrance, past the replica prairie wagon, feeling a sinking in my chest because these accessories are for my late grandfather's model tank, and they help me remember him. I kept retracing steps along the gravel path near the museum's visitor center and the benches near the art exhibit. If someone found them, I would be grateful beyond words; it's not just parts, it's memory.
