  Three versions of the Nombrex Type 27 were produced: the first version used unscreened RF coils as shown in image 5, the second version had screened coils and pale grey knobs as shown in image 2. The third version had minor circuit revisions which divided the AF O-P between the outer and inner of the AF O-P socket, and increased the RF output impedance to about 10k Ohm at maximum setting of the control. The knobs are now the narrow black skirted type with a similar black knob on the tuning control. Your schematic shows Version 3.
