TDC Model B 35mm slide projector. The projector its metallic grey in color and stores in the neaat, tweed fabric covered wooden case seen in the images. It is in excellent condition and works great! You don't need slide trays, just load a slides in the carrier and spin away. I used this to preview my old slides as I scanned them, job is done and I don't need it anymore. My Dad bought this in the 50s. The bulb is in the machine and does work. This an excellent vintage item to own.
