The development of shipping containers reached a turning point in the late 1970s when standardization began to take place. Prior to this time numerous designs and sizes of containers were seen throughout the world. The true intermodal era began in the 1980s with the expanding world economy, Panama Canal ship size restrictions, intermodal railway car (wagon) designs and the setting of ISO standards for international shipping containers.

In addition to ISO size standardization, assembly-line manufacturing standardization brought the steel container from various aluminum and steel designs to a more similar design. In the late 1970s squared corrugations with double logo panels were common new-builds. The next step, occurring during the early 80s changed the squared corrugations to a beveled design. Finally, in the late 80s, the logo panels were no longer seen on new-builds and the all-corrugated side container emerged as most production was shifted to China.

Master Model Features:

• Prototypically accurate "beveled" all corrugated sides
