Ordered a single dome Dad's Root Beer tank car. It arrived with the upper safety rail broken in three places. Anyone know if this rail is available as a replacement part or am I just out of luck? (it looks like the same rail as on the current tank cars)

I need the part number for the safety bars or mud guards for the underside of a large scale closed street car. Dropped one of my trolleys and broke these. They are the bars in front of the wheels with all the little u shaped things on them.

Just bought a green and cream color trolley with German writing on the side. It is the same design as the Hershey and the regular G scale closed car trolleys. Any one know when these were made,were they a production item or is this a proto type of some kind? I can not find one pc. of info on the net. Thanks in advance, Mark
