The 1950’s model featured is owned by Terra Clarke.
This second very early 1950’s Model 140 is is owned by Mike Hyrczyk, Pittsburgh, PA. He acquired it in November 2014 from the Pittsburgh craigslist. It belonged to a young lady from the Oakland part of Pittsburgh near The University of Pittsburgh. She said it was her grandfather’s. It has the mount that is bolted directly to the OTA and a lens cell with no markings indicative of early to mid 1950’s. The updated cradle that replaced the bolt-on mount was first introduced in an advertisement in the August 1955 issue of Sky and Telescope magazine.
