Description:

Pictured above is a preproduction version of Heavy Duty as the figure appeared on a product insert catalog. The most notable difference with this figure is that there are swivel joints located above both knees. Also, the forearms have green inner detail rather than black and the belt buckle is unpainted. The waist is also shaped slightly different.

Additional Images:

The same figure appeared at several conventions, but with a painted belt buckle and bazooka.

It also appeared at Hasbro's official website.

While several production-level hard copies of Heavy Duty with this color pattern have become available to collectors, it is likely that these were produced in quantity by the workers at the factory where G.I. Joe figures are produced, rather than actually being created at Hasbro's request. It should be noted that these Heavy Duty figures do not have the added leg articulation and also feature the same waist mold as the produced figure.
