It is near position 44, when I can post a picture you will be able to see what I mean. I have no evidence that they were not plated over from new. It would be a strange thing to do, the Decca hole son the left side are sometimes plated over so I just assumed that they served some purpose.

et voila, now that I have wittered on for 10 posts maybe this will work
Hurrah! The top image shows my HU5 panel with Decca, I hope to do something suitably retro for the right hand side. The lower image shows a right hand side with no blanking plates so I am interested in the contents of the rightmost column of three holes.

Smirky, I've asked one of the guys at HH to send me a picture of the cockpit - I'll post it when he does.
Remembering the back story of the HU5 it is entirely possible that the unpopylated instrument panel shares a part number as far back even as the S58 from which the HAS1, HAS 3 and others were derived. If so the holes may have been populated on earlier marks, but not needed on the Mk5. It would be cheaper, and better logistics in service, to produce common panels and populate the unused holes with blanking plates at aircraft production. A look at HAS 1, 3 and 5 panel part numbers in the Topic 3's might be illuminating. Similarly, if the hole fillers were wired there will be details in the wiring diagrams, Topic 10.
Thus opening 20 might indeed have been a cable out indicator on the 1 and/ or the 3 but was not needed for the 5, so was always fitted with a blank.

Nutloose, thanks for posting. The first picture is XS511 where you can just about see the usual arrangement with the small ammeter and the blanking plates. Very unusual thing bolted over the clock hole !
The others are XT761 at HH and the bottom picture shows the area of interest with two large "ammeters" and something in the small hole at the bottom that is hard to see. If you compare with post 22 (lower), you can just about see that the cutout at 8 o'clock in the top hole has been blanked,

Oo yes, I can't see the link here but it is visible in your posting history. The "ammeters" do not move so maybe they are temperature, the small hole at the bottom has been blanked off on the back. This aircraft was used for ground instruction mind.

some about rad alts
What is it about the Wessex that makes people so fond of it?
what about the P1 instrument dimmer?

Great, that's nailed the ammeters, which aircraft is this? You can see the filled in cutout bottom left of the top ammeter hole but not the bottom one. (Also the centre Plastek doe not have the holes for the Fuel Transfer Warning dollseyes below the clock.)

I wonder if previously it had something like an altimeter in that position like this, the blanked off cutout next to the top ammeter would make sense then, see
