4-6-0 chassis part number

[ebayrr]

I have a yellow and black Denver and Rio Grand Western #177.  The unit has a bad gear assembly and I would like to make sure before ordering the chassis of the correct part number. It is also missing the tender's battery cover. Can anyone provide the part numbers for these items?

Anyone know what the model number and production date is for Ernies D&RGW #177 4-6-0

Thanks

This one will work, even has the correct colors on the steam chests.
