I found this article on Page 47 of the February 1962 issue. There was a companion building in another issue . It was a storefront add on to the prototype elevator. I will have to search for it.
The companion building to the grain elevator was in the July 1961 issue of Boys Life.
It was titled a Farm Supply Store. It was evidently Made to look as though it was a retail store attached to the Elevator.
