This unbranded 1/4” air ratchet has me stumped. Have literally looked at hundreds of pictures of ratchets and cannot find one identical to this model. Picture show each of the different sets of numbers on it. I know the number 14 on the lower end is typically for a 1/4 inch ratchet. Other markings on the ratchet hopefully show in the pictures. Google says it runs in line with either wright, snap on, blue point, ingersoll Rand. may be a couple of others. Untested because I did not have a fitting, that would fit.
