VINTAGE (1950's) GM CHEVROLET LOT PHOTO SLIDESw/CHEVY 3-D VIEWER-MODELS ETC

Offering a large lot of 43 Cards each displaying 6 slides on each side for use with the GM 3-D Viewer giving a Stereoview effect. The images comprise of the early Chevrolet models, interiors and accessories and issued by General Motors. The Viewer requires a little work to experience the full illuminated effect of the colored slides, namely: the large screw to hold the sides together is missing (pic.8) and perhaps there are other issues I'm unaware of. I thought the listing might be of interest to a collector/restorer, or one who enjoys vintage Chevrolet Models. Thank you for looking! PS: Please note I found the screw in the carrying case that held everything, however, it's just turning and not anchoring.
