UPDATE:  CapnJohn obtained the following info related to Selouki:

“We don’t have a photo of the front of this vehicle but this manual covers the Selouki 1/4 Ton Truck model 4WD-25T.This Jeep like vehicle was produced by Highway Products Inc, Kent, Ohio.

Highway Products, Inc., Kent, Ohio was formed by Joseph Thomas ‘Joe’ Myers in 1960 to manufacture truck bodies for specialty markets such as mobile post offices. In addition to mail trucks and mobile post offices the company also manufactured small boats for both military and commercial use, missile launchers and engines. In 1968 Highway Products introduced a 25-passenger bus and sold it under the Twin Coach name. Joe Myers sold the company to Alco Standard in the early 1970s. Alco Standard bought the Cortez Motor Home line of products and manufactured the motor homes in the Kent, OH production facilities of Highway Products. Approximately 900 buses were built under the Twin Coach name when production stopped in October, 1975, due to bankruptcy. Joe Myers also served as the President of the Davey Tree Expert Company and was married to John Davey’s granddaughter, Marilyn Davey.“
