In the book Amazing 3D it is suggested that Kodak abandoned its mounting service in 1955 and then resumed it after the demise of the Realist.Amazing 3-D, p. 51. In many stereo slide collections there are Kodak-mounted slides with handwritten dates from 1956 to 1957, as well as Kodak mounts with embossed dates from 1958 to 1971 and later. This suggests that it was actually the Realist slide mounting service that ended in 1955, as no Realist-mounted slides after that date seem to exist.
