Here is an O-Scale "junkyard" of parts and a built car.

This auction has a built all wooden O scale RDC or street car. Nice detail Great looking metal with springs trucks.Wooden car needs side windows installed and you can always install your own details.
The car has a nicely detaild brass with porcelain insulators on the roof.

Walther's RAPID TRANSIT cars have instruction sheet, die cast metal couplers, (2) CHAMP DECALS , NYC 20th Century Pullman passenger car.

I see some wood stock,a brass thin strip,a Vestibule and Walther brass 3/8" wood screw packet.

Thanks for looking !
