The reference becomes geometry.
Four CAD-driven exterior concepts with sculpted guards and tapered access towers.
Retained development study. Dimensions, names and checks belong to this revision—not automatically to the retrofit-only product. Manufactured tank shells are deferred. No installation instruction, certification or manufacturing release is represented.

The source reasoning
Why this detail was investigated.
This revision translates the earlier appearance reference into modeled surfaces. Shared proportions do not establish model-specific capacities.

Research record
The detail behind
the study.
Source-linked work for this revision. Reported checks describe the stated model or test; physical qualification and applicability to the current retrofit remain separate.
Deeper chamfered panels, broad single end panels, sculpted corner guards, softened edges and tapered access towers. All four views below are rendered from the revised CAD meshes.
