The object has been broken into parts. Two of those parts remain in the collection. They do not fit together, indicating that there may be additional parts that have gone missing.

220.1 One end is an uneven glass tube with thick walls that is jagged at the edges, indicating that it has been broken off from something. The tube becomes broader towards the broken end. At the other, narrower end, it is fitted into a short length of brass tubing, which is screwed onto another tube attached to a stopcock. Beyond this there is a narrower tube, a broad collar and a still narrower section of metal that narrows to a stubbed point. A length of thick wire is twisted around tube above the collar.

220.2 It is another length of glass tube fitted into a section of brass tubing. The glass section is even in width in the exterior, but uneven on the interior. The glass is broken roughly at the end. The brass tube ends in a large brass hook, likely to hang the apparatus.

Poor. The object is broken and parts appear to be missing. The glass is significantly warped and damaged. The brass sections are in relatively good condition, but the surface across the length is scratched. There is evidence of solder below the collar on 220.1, possibly indicating a repair.
