I do not keep a photo archive, sorry. However the following link contains a schematic of the Sweitzer Barn.
http://www.farmbuildingguide.org/sweitzer.htmlPlease note, different heights at the ramp and forebay walls and the post over the foundation on the forebay side. Also note the light wall framing in the forebay. At variance from the norm for Sweitzers is the roof slope of about 10/12, the normal Sweitzer slope is 12/12.
A Pennsylvania Barn has same height walls at the forebay and ramps sides. Roof slopes range less than 12/12 perhaps 10/12 to 7/12. Penns use full size timber in the forebay but often have support from the forebay adjacent foundation to pick up roof load.
A complication in barn roadside spotting is that often shed extensions on the ramp side mess with the profile view, so often barns must be seen from different POV's in order to get the right classification.
