I was just given a "whole darkroom" today and as I try to piece together the anonymous photo enthusiast whose gear I just took in...
One fact is clear. This guy knew his sheet metal.
One enlarger is a D2, and there's several "Omega" branded negative carriers. But there's also a few hand-made ones. Now I've made some out of cardboard before, and in the bunch there is one really ratty cardboard negative carrier. But three of them are aluminum sheet with pins/rivets and fairly well shaped. Home-made.
That doesn't really amaze me though. What amazes me is the box I found with almost a dozen tiny home-made Speed-Ez-El's.
That's right. Home-made.
At first I thought I'd found prototypes of the original... But this magazine blurb (lower-right corner of page) proves that these have been around since the mid 1940's.

And evidence dates my new "darkroom" to 1960. A sheet of paper with sketches of ways to cut smaller pieces out of a sheet of 8x10 paper... on the back of which is a memo to a certain vice president of a company that makes chimneys for gas furnaces, an address in a town not far from where I live...
So V.P. of a company that makes sheet metal products. Bingo. Now I understand. He must have been a talented sheet-metal worker, who worked his way up through the ranks, and happened to be a photo enthusiast.
Still trying to make sense out of the strange sizes he made these easels. My initial guess is he couldn't bear to waste the 2 inch strip that always seems to be left over.
