Does anyone know of a source for recoating mirrors?
I am restoring a Reflex Korelle with a really badly tarnished mirror. |

it's probably easier and cheaper to replace the mirror..... |

Old Polaroid cameras such as the Button, which can be bought on eBay for very little, contain a large front-silvered mirror which can be cut to fit. |

According to a thread on another forum, any of the folding Polaroid cameras from the 1970s using SX-70 film have the large face-silvered mirror. |

I suspect that mirror thickness is important, so I suggest that you check out any replacement such as the Polaroid to make sure that it is the same as the mirror in the Korelle or else proper focus could be a problem. |

Surface-aluminised mirror glass of 1.5m to 2mm is fairly readily available from mirror and glass specialists here in Australia.
BUT since it is all imported from USA you shouldn't have any difficuties in your New York neck of the woods.
My local Glass Merchant cuts me such to size for Rolleiflex and similar - for A$11. (Which is about US$7.80)
Conventional "back-silvered" mirrors are not suitable because of optical refraction through the glass thickness - which leads to slight double imaging in the viewfinder. |

Indeed -- ALL Polaroid integral-film cameras (that is, the ones which have the battery in with the film) have a mirror inside. I have used one of these mirrors as a source when I needed to cut a new mirror. It was for a rangefinder, so I needed only a small piece, but of course this would work just as well for an SLR. Just remember you might have to adjust for proper focusing.
Also I know at least some if not all of the little Polaroid I-Zone cameras have very small mirrors inside. |

I don't have a Korelle, but all cameras that I know of have at least some adjustment avaialble for a slight thickness difference. It's obviously best to get it as close as you can, but it doesn't have to be perfect. |
