Back in the late '70s and early '80s, the one-hour-photo craze swept the nation. Noritsu, a Japanese company, invented the "minilab", which is the industry term for a one-hour-photo machine (actually a pair of machines — a film processor and an integrated printer/paper processor.) For a few years they had the market essentially to themselves, until the inevitable competition (largely from a company called Copal) took notice and introduced machines of their own. Noritsu, however, continued to dominate the market.
The first minilab to be sold in the U.S. was the Noritsu QSS-2 system. In the early '80s it cost $100,000.00, not including the site preparation (water, power, etc.) or installation. Despite the cost, new locations popped up seemingly daily.
At the time I was running a camera store, and we merged with a photofinishing concern that had decided to get into the one-hour-photo game. I transferred over to that division to oversee the retail operation, which eventually expanded into several locations (and led to a short stint working for Eastman Kodak, but that's another story.) Our equipment was initially all Noritsu.
Each Noritsu QSS-2 system came with a complete service manual and tool kit — all Japanese tools, of course. The chief components were screwdrivers and nutdrivers, which were all sourced from a company none of us had ever heard of: Vessel.
Now Noritsu didn't spend any more money than they absolutely had to on those tool kits, so they bought the very cheapest models from Vessel. We all thought they were "Jap ****" (it was the Reagan era, after all), and generally griped about the cheap tools. But we had to admit they worked pretty darned well!
Somehow I ended up with one piece of a Noritsu QSS-2 tool kit, probably from our first installation in 1983. It's a Vessel 7mm nut driver.
Keep in mind this was used in a wet, corrosive chemical environment, and later stored in an unheated garage for several decades. It's actually amazing that it's still in such good shape — the handle and ferrule are still tight, and it fits 7mm hex heads (if you can find any) perfectly.
