Developed in the late 1950s and sold through Welch Scietific Instruments catalog, this 1964 Replogle mechanical orrery was intended to be in direct competition to traditional telluria and orreries. The base can be rotated which then turns and tilts the orb thus allowing one to demonstrate seasons, day/night, time-zones.
