This is a National WVP-100N saticon tube colour camera from around 1984. This camera had a few cool features, one was the picture negative effect so you can get the pictures inverted, this effect is makes an excellent video effect when pointing to the TV screen as on each feedback the picture is inverted which you get positive, negative, positive, negative visual feedback effect. Anyhow I had 2 of these cameras over the years, one died on me so it went to Cavions, the other works quite well and I've kept it. It's an excellent camera.
Below are a couple of video caps from this camera, the 2nd shot is the picture negative effect
