Hey Brian,
I know where a restored one is and it is in working original condition
Is the machine in nice original condition or has it been restored properly...?
Or has the machine been checked out and gone through to ensure everything is functioning and then had a nice paint job applied...?
If someone did a thorough restoration on a Mills 45, they spent some time and money! Without knowing the details, I'll go out on a limb and place a value between $4000-$5000 for something in excellent original functioning condition. An properly restored one would possibly fetch more...
