Mk-III "Black" Chassis |
The spacing for the coil plugs are not 0.75" like the crystal sockets but is closer to 1.0" based on B&W coil stocks. It is also painted black to match my 1935 National HRO radio's chassis.

That is because it is in the wrong hole, which is intended for a #6 screw to pass through, which is slightly larger than needed for the eyelet holes. It should be in the hole just above it. This eyelet passes the plate choke lead, and the second hole is actually intended for a ceramic standoff. In this hole, the stand off would interfere with the output coil, so it will be drilled out and a new eyelet rivet set in the correct hole.
The front panel mounts to the chassis so corresponding openings are also on the chassis.
The slight haze around some of the holes is from the glue that attached the drilling plan to the chassis for a drilling guide.
