Dave the rig that you are looking at was the Original 672, better known as "Big Mo". That was the Original chassis or shall I say the "wheels" of Big Mo when they were put in service in mid 1967. In about a year or so they had remounted the Deluge set onto a much larger "military surplus" style chassis which was similar to that of Big John which was 673.
The original 674 or "Little John" had a much smaller Deluge set on it.
