This is a vintage toy cast iron yellow cab made by Arcade. I believe it was made it the 1920's. I think someone may have painted the words on the doors after the fact because the lettering is not consistent in size. I imagine the original wording wore off, I don't know. Frankly, I don't remember how I got it. It might be my son's toy many years ago. I believe it originally had a man in the driver seat, but there is not one here now.
The cab is 9" long, 4" high and 3 1/2" wide (approx.). The cab has metal wheels. 
If you are a toy collector, then this would be a great addition to your collection.
