Dude, I just dug this up in my back yard:

Ambulance / Mercedes Benz / "Benz" Ambulance
(Matchbox series No 3, released in 1970. Made in England).



The version I dug up is extremely dirty, though. Most of the white paint has been chipped off, and the opening rear door is gone. It's also a tad rusty. :cough: But ths is pretty cool!!
