The cabinet swap contract is early 1950s as best I can tell. Contractor was National Electric Supply Co. which did specials for the Navy.

That TCS-12 contract is 1943. I sure wish I could find a list of Navy contract dates.

I got these photos from a Dutch ham. Don’t know whether that has any significance or not. More later.
