National PE-387S Auto flash unit
 

I have recently aquired a National PE-387S Auto flash unit complete with remote sensor, the unit is in excellent condition and I'm keen to put it to good use. I've already determined that it's trigger voltage is low enough, (7.8 volts) to use with my Nikon D200, unfortunately the flashgun didn't come with an operators manual, is there anyone in World Photography Forum who has a copy that they could either post on the forum, email or mail to me.

Thank's
