Is anyone familiar with the Ansco Memar Pronto camera? A friend of mine gave it to me, it's been sitting around a long time, it's full of dust and totally filthy. Not sure if it works. Is this camera worth cleaning and using it? What do you use to clean vintage cameras with? I have googled it and there are so many sites on how to clean a vintage as well as digital cams. Not sure which is the best method. Also the timer lever seems stuck. It's in the middle front towards the bottom. Any thoughts or suggestions?
