Intermountain PFE R-70-20 reefer

The "SPF" letters on the prototypes seemed to be ever so slightly larger than the existing "PFE" initials. This effect is replicated on the model using the Microscale decals, but it does seem to be more exaggerated than the prototype. The shield poking out from under the white box is a little off-putting. I might have to correct it later when I get around to weathering it.
