You need vehicles to flesh out the model world. I found these vintage vehicles suitable for Scale55 and 55n3.

The 1920 Mack truck is a Matchbox, Models of Yesterday. The other cars and trucks are Lledo, Days Gone By. The steam tractor is unknown and the IHC tractor is an Ertl 1/60. These are vehicles from my S scale days that were really too big for S.
Someday I will paint a figure.
