The box acts as a storage box for the viewer and has a three section storage compartment for stereo views. Exterior of box measures 8" x 7.5" x 5.5" high. There are two patent dates marked on the viewer, "Patented July 5 1870 & March 26, 1878." The first date refers to an E. K. Page patent for the lazy tong movement, while the latter date refers to a Lewis patent for a similar device in a box. This would seem to indicate some sort of business relationship between Page and Lewis. Refer Wing page 128 for more information on Lewis viewers, although this particular viewer is not illustrated. This unusual viewer is worthy of further research.
