Secret allied weapons of WW2

[Die Hard]

I know they had some nerve-gas, but they had a problem just containing it. Did they have the devices ready for transport and dropping it from aircraft?

Yes. Tabun was loaded into standard prewar C-series of chemical dispencers, usually the C250 bomb, and later in the war also in the AB-series of sub-munitions dispensers. Tabun wasn't more corrosive or difficult to handle than mustard gas. It was during production that the chemicals used to make tabun was so difficult and dangerous to handle. At the end of the war in Europe almost 71,000 bombs containing tabun had been seized by the British in Germany, these were stored in the open at RAF Llandwrog, near Caernarfon, until 1955/56 when, in Operation Sandcastle, they were transported to Cairnryan and scuttled at sea in three ships 120 miles (190 km) north-west of Ireland. I wouldn't go fishing there.

What I recall is that it was highly corrosive,  - and with the lethality vs mustard gas therefore equally difficult to handle as it's effectiveness. Weren't the tanks lined with silver or something like that?
Anyway, curious to know if they had it ready in aircraft bombs and then which squadron would have been assigned.

[Die Hard]

The intermediate products of tabun were corrosive, and had to be contained in quartz or silver-lined vessels. Tabun itself (the finished product) was less corrosive than mustard gas.

I don't like speculating half as much as you do Angus. Which unit would have gotten the dubious honor of delivering chemical weapons during the Battle of Britain is not really that interesting. Any KG could have done it.

[Angus]

Well, speculation makes a lot of fun, and gives you lots of angles. Speculation is in itself a process of the data available
Anyway, even less corrosive than mustard gas, the danger IF it gets out is so very very much more. Hence my speculation of it it was ever ready to be loaded into aircraft bombs. Were the bombs ready? If the bombs were standard, then of course any KG could have delivered them.
To make things clear, (from my speculations), I do not debate that had the Germans wanted to use this during the Blitz and decided so some time before, they could have. It's whether they had this at short readiness for air-bombing that makes me scratch my head, as well as who was pressing who and where in the high command about that deal....

[Die Hard]

Standard C-series bomb. Same as used for all the other chemicals they used including smoke and phosphor. The process of filling the bombs were dangerous of course, and there were several deaths at the production plants, but once the bomb was sealed it was as safe to handle as any other bomb. I don't think the Germans had any form of chemical weapon at "short readiness" at any time during the war; only in closely guarded storage depots. It would after all require a Führerbefehl to deploy these things.

Interesting. Thank you!
I am trying to dig up two interesting books I have, they are in German and from a series of WW2 related material available at some railway station book-stores in Germany when I was working there in 1997 or so. The subject was exactly secret weapons of WW2, one about the allied ones, and one about the German ones.
I was actually sitting on the toilet while reading about sarin

How very appropriate!

Oh, it wasn't THAT bad
