Post a few at a time here on the board and I will galdly share what I know. Our database of cameras have information on the camera to help identify models and indicate what time period they are from. Our Kodak section now has a collectable rating which will help in identifying the value to an extent. There is a wide range of camera values based on age, condition, historic significance and quality. Post your photos of the cameras and info here and we will try to help. If you have many you may want to price quickly, you can always just buy the price guide to help. to maybe you library will have it,
