This object is part of an apparatus for investigating air pressure in different locations on the surface of a wing model. This portion of the apparatus is the manometer. It consists of a wooden stand holding up two glass shapes. One consists of a vertically supported tube with an orange rubber stopper in the top. Protruding through the rubber stopper there is a small u-shaped tube open to the air.
This glass piece is connected via a rubber tube to a second glass tube set horizontally. Emerging from this tube are eight vertical glass pipes, one of which is broken off at the base and the hole filled with a white material.

Primary Materials: Wood, Glass, Rubber, Metal
On the front of the stand, a small silver sticker: “PHILIP HARRIS LTD
144 EDMUND STREET
On the flat base of the stand, on an embossed sticker: “ZOO . 220”. Another similar sticker reads, “RM. 136”.
Dimensions (cm): L=26cm x W=10.2cm x H=23cm
This is part of an apparatus designed to investigate variations in air pressure over the surface of a wing at seven points. The air pressure differences are visualized as changes in height of liquid within the seven tubes of the manometer.
Fair. The stand and supports of the object are in good conditions. However, the rubber tubing is degraded and cracked. One of the glass tubes of the manometer has broken up. The interior of the horizontal tube of the manometer is dusty.
