Pocumtuck Box | Custom wood boxes, cases and displays | Made in the USA. They had the contract for the SW presentation cases and maybe still do.
The CEO/Founder lived in Deerfield, Mass, where I was a police officer, and I met him one time when I was patrolling the area where the old factory was located. He was kind enough to give me both a large and small presentation case of the new design. Both are quality cases and were stamped with the SW logo.
He might have an older one at the old factory location. They were listed in the SW factory store catalog at one point. I'm sure you can order a new generation case from them. Click the link above.
Good luck.
