Here is an interesting little screwdriver set with bit storage in the handle. It is marked "Humphrey Tool Co. / Warren Mass. USA / Patent Applied For" on the walnut handle. The bits, stored in the handle which has 11 marked positions 0 thru 8 plus P & S (0 is the non-hole), have square-to-round shanks which fit into the square hole in the collet. The long brass cap has a round hole and simply screws down over the bit until it jams on the squared portion. Tools include screwdrivers, a gimlet, a square awl and a spike.
