Identify this truck ?

[brien]

The attached picture is my grandfather sitting in the US Mail truck he drove in the first years of the 20th century. I can't make out the name of the vehicle. It is obviously a chain driven vehicle early model truck. It's not a Ford and there is a name off to the left just besiode the brass lamp..Can anyone identify this vehicle? Click on the photo for a larger image..

Thanks for looking here.
