| Abstract: |
U-tube, sealed at one end and open at the other, on a brass mount, silver gilt in part, inscribed at top 'Cappy et Mossy'. The open end of the tube has been rounded in flame. The scale is marked on the mount and the tube is attached to the mount by means of three brass hooks screwed to the frame and thickened at the base. A label on the back has what looks like '36' or '36'. |
