It is somewhat strange that you can have a company build an elevator, but there can be differences between two separate models. The Byers, Colorado, elevator was built by Mayer-Osborn. This model has the manhole covers on the outside of the bins, whereas the McAllaster, Kansas, elevator has the manhole covers on the inside. You will notice the manhole covers on the outside of the bins in the Byers view. Plus, there is a walkway door about halfway between the bins. The window arrangements are slightly different between these two elevators. Basically the driveway is the same on the two models.
One thing stands out like a sore thumb: whoever painted the Byers elevator painted the manhole covers. This is the only elevator where I have seen this done. Generally the manhole covers are not painted.
It would be the option of the Co-op what was wanted in the elevator. If the owners chose more options, of course the price of the elevator would increase, too.
There are two sides of an elevator. One is the track side, where the railroad tracks are located. The other side is known as the drive way, where the trucks will dump their loads.
I do not believe that the McAllaster, Kansas, elevator has been used for some years. The steel bins were empty, when I photographed here on November 14, 2011. The weeds were fairly high, and the rail spur has been removed.
