I try to use the ~1962 designation as I have a complete list, anything after I only have partial Snapshots of changes.

In the snipit from the Census 254/71 Salamander Street doesn't have a number but in 1962 was listed as 13-D Bath Street so may have only been retained for the Siren?

6-D reference is taken from the Carrier planning document that was produced in ~1962.

However, following up what you said, The same box is is listed in the 1970 "Census of Pre 1947 Sirens" as "254/72 Police Box 2 'D' Henderson Gardens, Leith"

I assume there was a review/renumber in the 60's?

If analysis justified a fallout warning the Group Warning Officer would pass this to the CCP after which the post would get the message via the WB1401.

You could pass the warning as a non-routine message to the posts (WO to Post Display Plotter then on via AD8010) but this involves extra steps.

Wb1401 is connected back to the Carrier Control Point (unidirectional speech) its only function is passing warning messages.

AD8010 is connected back to Group (two way omnibus circuit) it's passing information upwards for plotting and scientific analysis.

I did, I would argue, as it was part of the Reporting System rather than the Warning system, it doesn't need to wait for a Saturday (Only for me to have a free moment)!

I also have pictures of the earlier AD3460 (But don't think I have a AD163 Headset).

They upset me with exactly this. I was paying more for the lowest speed than a new customer would get for one of the highest.

When I enquired about an upgrade it was were only a couple of pounds more for double speed but I needed a new Router which of course came with an installation fee.

"The police box on Maybury Road would be relocated and we would like the community to suggest what it could be used for."

"2. Police box would be relocated."

I am keen to make sure any redundant Siren Equipment present is removed/preserved and not scrapped.

The box does need lots of TLC but it would be a shame if it cant be moved and goes to scrap.

If it still has its original interior I would like to document it for traces of Siren control equipment. If any equipment is present I would be in a position to negotiate for its removal & preservation.

I am not actually sure.
I believe, but can find out, it was some sort of stamped metal.
The Prototypes were Bakelite type plastic and broke far too easily.
This is one of the best finishes I have seen on one as the finish on most has bubbled or flaked.

Question about the building that was rebuilt as the R30 (The WW2 Happidrome/Final GCI).
In the Late ROTOR Period (1955>) was this the location of the Eastern Sector Filter Room (CFP)?

Aye they were hiding, I was able to follow it for a bit on ADS-B exchange by playing with the filters but as soon as it goes out of range of what ever detector it vanishes.
It looked to have circled Pilton, Calder Road, Niddrie(ish) and then Clermiston before I lost it.

I am starting to get dizzy watching the Police Helicopter circling Calder Road, it has managed to drown out the fireworks if nothing else
