I think I got this one, a section of, from Pacific Wrecks. It may show the Radio access behind the opening I made. View attachment 497484
IMHO that's not the access panel to the radio compartment. Just that's a piece of the plate skin cut out from the fuselage . It seems tha the access panel is the one you replicated. Here shots of the stencil at the access panel and the fuselage interior behind the bulkhead in the cockpit. The radio panel can be niticed on the righ above the corraguted part of the fusealge structure.
