Accession Number: 2018.ast.66.1-2
This is a metal instrument on a cylindrical stand with a round metal base. On top of the stand there is a cylindrical metal piece, mounted with the barrel horizontal. On one flat end of this there are two protruding pieces, each with a knurled knob attached. On the other side, there is a flat piece with screws set in its surface. This piece is a different colour from the main part of the barrel, suggesting it is a removable part.
Associated with this object is a conical attachment (66.2) that is stored tied to the base of the object. This conical attachment may replace the removable part currently attached to the object. The cone part of this attachment is painted black with a metal interior.
The object has been covered with a lacquer, giving it an orange appearance.
Primary Materials: Metal
On the barrel shape: “17”
On the base of the stand, painted on: “13”
Engraved on the inside of 66.2: “178”
Dimensions (cm): Height =16, Diameter = 7.5.
This object is likely part of a larger piece of equipment of unknown use. It is possibly part of a photometer. It was likely intended to be used alongside 2018.ast.64 (a variable resistance box) and 2018.ast.65 (voltage switch).
Very Good: The surfaces of the object shows little signs of use, with the lacquer worn off in few places. The black paint on the cone attachment is chipped in places.
Associated Instruments: 2018.ast.64, 2018.ast.65.
Manufacturer: P.J. Kipp, Delft, Holland
Date of Manufacture: 1930s
This object was likely moved from the David Dunlap Observatory in Richmond Hill in 2008, upon the sale of the observatory. It was stored at the Department of Astronomy and Astrophysics until 2017, when it was moved to a new storage location in McLennan Physical Laboratories.
