Nikon SB-26 manual

[cdw3423]

I just got my SB-26 from ebay. Does anyone know where I can download a manual in pdf format for the SB-26? Also I noticed the external battery plug has 3 pins. Does anyone know what the 3rd pin is for? It is shorter than the other 2. I wanted to make my own external battery for it.
