Hi Jeffery,
The Marconi monitor is in better physical condition than the other one but there is some evidence of a few components have been removed, the B12A tube socket for example.
The monitor with the rusty cabinet is an all transistor model made in the USA by Conrac in California. The CRT is a Mullard AW36-48. The line output transistor is a BU106, European devices in an American product.
This monitor was made for 250volt 50 or 60Hz mains supplies.
