These are both vintage tin plate vehicles that were made in Germany in the 1950s. The fire truck (fire engine) I found on a website and it was identified as a Johann Hofler Fire Engine. I found the other one in blue on another site and it was identified as a Penny Toy.  Anyway, I can tell you that both of these are a little over 2 3/4" long.  The paint on the fire truck is much nicer than the bus. On the bus, I can see some scrapes across the top. I see a dark rub on the top of the bus one too.   The bases have darkened a bit.   These are hard to find. I will wrap them up individually and ship promptly in a nice, small box.     Smoke-free, pet-free home.  Let me know if you  have any questions.
