I had a friend give me a Kodak Retinette (circa 1954) that he has lying about. It has some kind of "Film advance not working problem". Turns out it was a "Shutter gunked up from 50 years of use" problem. Well this weekend I tore into it, gave it a quick Clean/Lube/Adjust and now I have a completely serviceable camera. I still have to set the focus more precisely, but I am sure it is working just fine. I am so proud of myself I had to share it.
