Vintage rubber dolls / plastic squeak toys, 50s 60s baby toy collection

Lot of five mid-century vintage rubber or plastic (vinyl?) toy animals and a policeman baby kewpie. Some are marked (Sun Rubber, Edward Mobley).

All have been well loved and are very worn and dirty, and I don't think most of the squeakers work. The tall yellow dog is the largest, and he measures about 5 3/4" in height.
