Yes Sir, this is the Eberspracher BA-6 gas heater.  It is most rare to find for sale.  And to find one as a complete set with all the items one needs to have it work.

  Members of the Seattle area,

  I have a complete set of original Vanagon heater that was used for the early vans.  
  I am in the Seattle area and am not going to ship it.  So it’s for local pick-up.  

  This heater works off the from the gas tank’s fuel, made of stainless steel and is to be fitted to the underside of the van.  All the electricals and fittings are with it.  The Bentley manual is a great help in knowing what to do with it.  
  It is winter and this is the time to fit it to your van and have hot air blown into your van while even if it’s standing, engine not running.  
  It would cost a fortune to buy it new, but I would let it go to anyone who gives me a decent offer.
