This hard to find knitting needle gauge is carved of real ivory. It is drilled with holes of different sizes so you would know the sizes of the unmarked knitting needles of the day. The sizes are all marked with engraved numbers that have been stained with a scrimshaw like technique. It is marked for knitting pins from size 1 down to size 20.
The condition is excellent with no chips, cracks or other damage and the ivory grain is nice. It measures 4 1/4" by 1 1/4".
