I have lost the instructions for my Stanley photoelectric timer, Model 51217. I have tried the manufacture National Christmas Company at Welcome to The NCC (http://www.thencc.com). The site in not active. Any help would be appreicated.

The site must have been down when you tried, as I was able to find the manual there:
