Which Sleeper Is On This B Model Photo Taken In The 60s?

[bamlogisticsinc]

The Truck was a B Model by General Split Corp in Milwaukee, WI. 

 

The Sleeper is noticeably shorter than other brands, sitting right at the height of the cab, Also has a painted square shaped vent. Unsure of the brand of this sleeper. Photos were taken in the 60s, I would assume its a factory option.  Interested in one of this brand with the same dimensions. Can someone point me in the right direction? Maybe its possible someone here owns one of these B models from the former General Split Fleet? 

 

Thanks, B.

Information on sleepers of this vintage is essentially non existent. There were dozens of independent sleeper manufacturers back then. I would say not a factory option. Back in those days if you wanted a sleeper you put it on in the aftermarket.
