I accidentally threw Steve down the rabbit hole, and here's what he came up with from the one photo (top one) of a 1937 Ford delivery truck used on a country wide delivery route known locally as a "Huckster wagon"

Steve had mentioned to me that he was collecting photos and or stories of panel delivery wagons, and I was curious when I came across this photo last night if it was something he was interested in. Yup. 

this article was in the September 27, 1937edition of "The Noblesville Ledger":
