I'm in search of metal roofing and/or siding off a Butler frameless farm building. Buildings were popular in 70's and 80's. Willing to disassemble storm damaged structure. Distinguishing characteristics are deep (3-3/4") profile, ridge beam only support and heavy base angle. From what I know, buildings were typically 40' x 60'. See photos of panels and base angle. I'm in desperate need to finish a hobby shop under construction.
