Tray-Stereoscope ‘Série I’

The wood­en trays con­tain 25 slides each and can be insert­ed into the view­er by flip­ping back its top. Then, by turn­ing a crank on the right side of the hous­ing, one slide after anoth­er can be exam­ined. Each half-turn of the crank advances or returns the slides and moves the tray for­ward. A met­al lever inte­grat­ed into the counter on the left side of the view­er enables free slide nav­i­ga­tion. The ‘Série I’ includes a wood­en cab­i­net that holds up to 12 trays, accom­mo­dat­ing 300 slides.
‘Hemdé’ view­ers are among the rar­er tray-stere­o­scopes, and are tes­ti­monies to the remark­able diver­si­ty of French stereoscopes.
