Geometric Model by A. Harry Wheeler, Measurment of a Spherical Angle

Description:

This cut paper tan model consists of two pieces showing circular discs with a projecting tangent plane at the top, as well as a paper ring of the same diameter. The ring fits in the intersecting discs to show how one measures a spherical angle. Two stickers read: MSA*. Another mark reads: Pat 1,192,483.

Compare MA.304723.156, MA.304723.671, and MA.304723.663. For pattern, see 1979.3002.087.
