Vintage Argus Canadian slide previewer

beautiful teal colored (more true teal then in photos) vintage slide previewer. slides go inside and you can preview them before using them in a slide projector. neat piece in great condition. comes with original box thats in fair condition (age, wear and tear and some pencil writing on the bottom as shown in 3rd photo) comes with a bulb to illuminate photos but that function is untested. I sell a bunch of variety of items, please check out other closet listings, and if you see something make me an offer! thanks
