Seeing that the mini-vehicles are very popular, I've developed this set of Divco Twin vans with different color schemes. They'll have small capacity and will be available from 1933. I haven't decided yet if they are going to transport mail or piece goods. It'll depend on mail transport popularity..

Done... 7 vans from 1933 to 1955. Capacity: 10 up to 16. Around 60 km/h of max. speed
