Vintage New Old Stock (NOS) 4H-V9.6 Selenium Rectifier.  This is a single plate two wire Selenium Rectifier that has both male and female connectors for the red wire lead.  I'm unsure of the maker.  It's probably from the 1960's or early 1970's.  My best guess is that it is from a Gemini mini bike / minicycle, Honda, Hodaka or other small motorcycle.  Buyer to pay shipping to your location.  Will ship worldwide.  Will combine shipping on auctions.  Will gladly accept returns if buyer is unhappy with items.  Thanks for looking.
