Yeah, the CG had S62 A's and B's though both were called the HH52A.
Even after putting on the nose radar they were still called the "A", go figure.
More powerful engine? What could be more powerful than a GE T-58 engine circa 1959-60?
Maybe a more powerful transmission? The T-58 had to be detuned so the airframe could handle it.
Looking at the main mount though it looks as if it is reversed for the tie down, I'm not sure if the civilian version had this done.(?)

I know it's only rock and roll, but I like it.
