These are two viewfinder frames for a Polaroid CU-5 Close-Up Land Camera. Both consist of metallic brackets attached to a square piece cut with a large circle opening that can be attached via two screws to the lens piece of a Polaroid CU-5 camera. 2019.ast.166.1 forms a box that is open at the top and bottom, and has a square cut in the front. This is marked as “2X FRAME” on the base. 2019.ast.166.2 has two side-pieces, like blinders, and is marked “1:1 FRAME” on the base.

On the base of 2019.ast.166.1: “2X FRAME”
On the base of 2019.ast.166.2: “1:1 FRAME”
2019.ast.166.1: Length = 10.3, Width = 8.2, Height = 8.1; 2019.ast.167.2: Length = 10.3, Width = 8.2, Height = 11.7
These viewfinder frames can be attached to the front of the Polaroid CU-5 to enable easy focusing. Each is for a different camera setting: these two are for the camera with no extensions via ratio multipliers (1:1) and a single ratio multiplier (2x). A third piece is currently attached the Polaroid camera lens (2019.ast.165).

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.
