I have one of those, it is actually model 61. I don't know why Majestic did that but the model 60 chassis was used in a few models such as 61 and 62.
I paid a hectobuck for mine, which is much more reasonable.
The chassis is two chassis clamshelled together. the radio is on top and the power supply upside down underneath. you can see the 80 rectifier peeking through the hole in the upper radio chassis.
It weighs a TON! get a second strong back to help move it!
