All awesome-looking pieces of furniture-grade craftmanship! Back when I was a kid, Dad & I went to visit Pachmayr in LA. Dad measured their popular pistol range box & made one from English walnut grown on our property. It was a beautiful box & I have it today. The only drawback was ... it's really HEAVY.
Weight is a problem with range boxes, since the bigger the box, the more junk you're gonna load into it.
I amassed a collection of old insulated zipper lunchbags over the years, and use them today. I have one for cap & ball revolver, one for flint rifle, another for percussion rifle, another for smothbore, and even one for .45-70 Trapdoor. Each one contains only what is needed for the particular shooting I'll be doing that day & I can haul along several bags as needed - they pack well into tight space behind my truck seat, and I can bring them out one at a time as needed for use.
