Panther/Jagdpanther Swappable Hulls

After picking up the Panther/Jagdpanther boxset (GBX84) from Battlefront, I wanted the option to make 10 tanks instead of 5. As there are only 5 lower hull assemblies in the set, I needed to come up with a solution to make the upper hulls swappable. After seeing other people do this, I came up with a relatively simple solution to accomplish this.

Sturm-Infanteriegeschütz 33B

The Sturm-Infanteriegeschütz 33B was a German self-propelled heavy infantry gun used during World War II. A new, fully enclosed, and heavily armored boxy casemate superstructure was built on the chassis of the Sturmgeschütz III. It mounted the improved sIG 33/1 infantry gun, offset to the right side, for which 30 rounds were carried.
