This dip circle is from that early period period. The vertical circle is suspended from a brass hook attached to a rotating knob, and so can be turned in any direction. The horizontal circle, on top, is graduated to single degrees. The vertical circle is graduated to 30 minutes; the glass covers are missing. The inscriptions read "Lerebours à Paris" and "W.U. No. 2"
