David;

The RF board is multi-point soldered into the outer frame, amongst other things, not quite mission impossible, but..... There are three screws going through it into the screening die casting shown in image '48. One screw has to be removed to take the outer "tinplate" screen off to gain access to the print side of the RF board, removing the other two results in no movement. I wonder if there is/are others coming into the screening die casting from through the front panel? If so getting to those would be, shall be say, "interesting".

As you say a proper receiver, in fact all in all, a proper job. All that's needed now is to find that pesky test point; which is why I tried to remove the die cast screen to see what is below; but, considering matters, it would (or at least should) have to be easy to "get at" for initial setting and / or subsequent re-alignment. Well in theory anyway.
