The stowage configurations appear from photos to be consistent trough the entire life of the vehicle, meaning the tanks were apparently never changed from one type to another. There is a photo in the Gannon BOOK showing the two types side by side during the Six-Day War, indicating the two types were build at different plants at the same time, or at the same plant right after each other. This is unlikely however, as the production of the M-51 spanned several years.
All M-51s build on welded hulls appear to have the M-51 type stowage configuration. At least I have never seen any pictures, either from museums, or during active service of welded hull M-51s with the M-50 type stowage.
Some stowage details are common to both the M-50 and the M-51 type stowage configurations.
- two smoke dischargers on each side of the turret.
- two road wheels on the left rear hull side, above the idler wheel.
- brackets for holding a coil of barbed wire on the front.
