No doubt showing my ignorance here by something everybody knows, except me, and I have searched Pratts, McCoy, Parsons, Rythers and a couple other names of chucks and none are exactly like this one. I am sure (100%) that this is a common chuck, but the name eludes me....
Chuck came on a Mohawk Shelburne hand drill.
There is a total of 9 parts: 3 jaws, 3 springs, internal cap that goes over the jaws which the pinion shaft fits into, the screw on cap towards the drill that has a "screwdriver" slot in it and the chuck housing which has no set screw. The entire chuck is about an inch and five eights long and has no markings. I have looked at many pictures, especially in Millers Falls Home Page and the description is a "3 jaw chuck".
Also, I have seen a M/F #94 with no name imprint on it. Does that sound right? And, it appears to have the same chuck as the one described above.
Don't heckle me too much!
