The model E viewmaster viewer was produced in several countries; Belgium and the USA are the most common to find. For a very short time this viewer was produced in Spain also. These viewers are hard to find. Although the viewer looks like all other model E's, the Spanish-made version is clearly different. They are always black in color and with a red advance knob. Most striking difference; the Viewmaster logo is upside-down!
The construction of the Spanish E viewer is inferior to the USA and Belgium manufactured versions. The two halves of the viewer body do not meet as precisely and the viewer is considerably lighter. Even the red advance lever is of lower quality The seam line down the side of the lens is also more pronounced.
The viewer on offer is in a very nice condition. Complete with Spanish box (viewer is called VISOR), all in very good condition.
