The EH sounds absolutely brilliant!! Where did you find such an original machine??
It came from Sth Aust originally,  was a St johns Country car,  I got it from the gold coast from the guy who had shipped it up here,  
was just luck that i got it, as it wasn't advertised as an Ambulance,  it was only when i rang up about it that he mentioned it
I dont know if it would be inappropriate to post a few pics up here for you?? 
but here's a little teaser,  sorry for those that think its inappropriate
