Pat pending n70. Still working very smoothly.
I have an N-70 like yours. Seems almost singularly scarce. Unfortunately, mine is trashed. Sort of. I have the arm, the shifter and its spacer, two screws, two pawls and their spring, one ball, the head base? Am I missing something? Do you still have yours? Have you taken it apart? Any advice?







Nice find and I approve of your supervisor.I found a Wright N-70 ratchet that was made in 1952. Has a round, knurled, selector switch. It is marked patent pending (likely referring to patent US2715955A applied for in 1950, granted in August 23, 1955).
It didn’t function. I took it apart and found the guts strewn about inside. I straightened a bent spring, cleaned and lubed, and used the patent drawing to figure out how to reassemble. Now it works fine.
(10.5” overall length and marked “Wright Barberton-O-USA N-70 Pat. Pending 52-" )

Those tools need a Cat scan before further diagnosis, and treatment can happenNice find and I approve of your supervisor.

Do we have photo image(s) of the green boxes and/or the red boxes?Can we determine when Wright changed colors on their socket boxes? I think they went from green to the two-tone black and gray at the same time they changed their drive tool numbering scheme. I have no evidence for when they went from the two-tone scheme to red.
Sure do. Just scroll in this thread and you'll se examples. OTG had this set in a green box in post 327 and genog had an example of a red box in post box in post 466. There are others. The green, if I had to guess, runs from post WWII until the early 1960s when Wright went to their new model number scheme. The red boxes maybe starting in the 1980s?Do we have photo image(s) of the green boxes and/or the red boxes?
Answering some of my own questions... we know from visual evidence on Alloy Artifacts that Wright started their renumbering scheme (at least for their drive tools) in 1959 and the box containing the "60" marked tools is of the two-tone black/silver variety. The 1957 catalog shows the older style rounded socket boxes in (presuming) the green color. So, two-tone started sometime between 1957-1960.Sure do. Just scroll in this thread and you'll se examples.
