I was in the museum the other day and was asked why there is a "square" on the pilots doors.
In Vietnam, it was a practice to paint triangles, squares and circles on the doors to differentiate between which aviation "company" within the battalion the aircraft belonged to. Thus the triangle belonged to "A" Company, the square belonged to "B" Company, and the circle to "C" Company.

60-6029 sn 702 also served as the testbed for the installation of the T53-L-13 engine, which is the significent change making it a H model.

This airframe was used by the Army to test various armament configurations. In 1965, Bell “bailed” or borrowed 60-6030 SN 703, installing two Continental T72-T-2 turboshaft engines in a module driving a common gearbox and called it the Model 208. Totally funded by Bell, it proved the concept of dual engines in the 205 airframe. But the Model 208 was not pursued.
60-6030 was returned to its original configuration and returned to the Army. Today, it is in the center of the main exhibit hall of the Army Aviation Museum, Fort Rucker, Alabama in a diorama based on a much publicized combat photographers photo from Vietnam.
Several years later, Bell again experimented with the concept of a dual engine version, this time using the popular PT6 engines from Pratt & Whitney Canada (PWC) and funded largely by the Canadian government. This arrangement became the Model 212 or UH1N.
YUH-1D 60-6029 SN 702 set several world records, looking closely at the photo you can see that many openings are taped over, some components had not been installed (windshield wipers, airscoops, and cargo door handles) to reduce drag. On the nose are painted names, probably the pilots wife and children. Most prominent is the serial number, often temporally painted on the nose to easily identify the aircraft on the assembly line. I have heard reports that this airframe is the one on display at Fort Sam Houston Texas, I would appreciate hearing from anyone who can confirm this.
