Tray-Stereoscope ‘Multiplast’, First Version

The Mul­ti­plast close­ly resem­bles the Tax­iphote in appear­ance. The 45 x 107 mod­el was oper­at­ed by a lever. The lat­er 6 x 13 mod­el used a crank mech­a­nism and allowed bidi­rec­tion­al nav­i­ga­tion. The Mul­ti­plast was con­tin­ued by Zeiss Ikon after the merg­er of ICA.
