The "Brand" 4x5 "field" camera. The thing makes an RB67 feel like a Ricoh GR1 in your hand. The handle on the rear standard gives the illusion that you could somehow hand-hold this beast. The dual-rail chassis design is also something that could get mis-aligned, and due to the fact that all the standards and the tripod mounting block are cast metal bits, if they got bent (say, you dropped it on a concrete floor while trying to mount it on your tripod) there'd be no way to accurately re-align them or to repair the camera to any degree of precision.
